There is an issue that link reset can't recover PHY when STP link timeout.
Because current process of enabling PHY for v3 hw will wait last
transmission done. The time of one transmission depends IO size, disk model
and so on. Normally, it should be shorter than 50ms. But the last
transmission could be never done for some abnormal scenarios, such as STP
link timeout.
This patch is to fix the issue. Check PHY status after starting process of
enabling PHY for 50ms. If the PHY is still active, we disable it forcibly
by PHY reset. Of course, we need to clear the PHY reset bit when enable
PHY.
Besides, the function disable_phy_v3_hw() should not be suitable to call in
interrupts for hilink bug for this 50ms delay. Then, we do link reset for
hilink bug directly. The change is that we don't clear the invalid dword
count register. This is better. Because we should not clear such error
count while not saved.

As such, remove this function and associated code. For v1 hw, move error

We don't want to use 'struct timespec' because of the y2038 overflow
problem. The overflow is not actually an issue here, but it's easy to
replace with 'timespec64' for consistency. However, it's worth pointing out
that nanosecond values have nine digits, not eight or ten, so I'm fixing
the format strings accordingly as well.

When calling either fc_rport_logon() or fc_rport_logoff() during rport list
traversal we cannot use the RCU list traversal, as either of these
functions will be taking a mutex. So we need to partially revert commit
a407c593398c to take the disc mutex during traversal. We should, however,
continue to use krefs to ensure that the rport object will not be freed
from under us.

rmmod of driver hangs
As driver instances were being unloaded, the NVME target port was unloaded
first. During the unload, the NVME initiator port sent a heartbeat
IO. Because of the target port state, that IO was scheduled for an Abort;
however, that abort subsequently failed. The failure was not cleaned up
properly and lpfc_sli4_xri_exchange_busy_wait silently hung forever.
