'pchunk->bitmapbuf' is a bitmap. Its size (in number of bits) is stored in
'pchunk->sizeofbitmap'.
When it is allocated, the size (in bytes) is computed by:
size_in_bits >> 3
There are 2 issues (numbers bellow assume that longs are 64 bits):
- there is no guarantee here that 'pchunk->bitmapmem.size' is modulo
BITS_PER_LONG but bitmaps are stored as longs
(sizeofbitmap=8 bits will only allocate 1 byte, instead of 8 (1 long))
- the number of bytes is computed with a shift, not a round up, so we
may allocate less memory than needed
(sizeofbitmap=65 bits will only allocate 8 bytes (i.e. 1 long), when 2
longs are needed = 16 bytes)
Fix both issues by using 'bitmap_zalloc()' and remove the useless
'bitmapmem' from 'struct irdma_chunk'.
While at it, remove some useless NULL test before calling
kfree/bitmap_free.

When hns_roce_v2_destroy_qp() is called, the brief calling process of the
driver is as follows:
......
hns_roce_v2_destroy_qp
hns_roce_v2_qp_modify
hns_roce_cmd_mbox
hns_roce_qp_destroy
If hns_roce_cmd_mbox() detects that the hardware is being reset during the
execution of the hns_roce_cmd_mbox(), the driver will not be able to get
the return value from the hardware (the firmware cannot respond to the
driver's mailbox during the hardware reset phase).
The driver needs to wait for the hardware reset to complete before
continuing to execute hns_roce_qp_destroy(), otherwise it may happen that
the driver releases the resources but the hardware is still accessing. In
order to fix this problem, HNS RoCE needs to add a piece of code to wait
for the hardware reset to complete.
The original interface get_hw_reset_stat() is the instantaneous state of
the hardware reset, which cannot accurately reflect whether the hardware
reset is completed, so it needs to be replaced with the ae_dev_reset_cnt
interface.
The sign that the hardware reset is complete is that the return value of
the ae_dev_reset_cnt interface is greater than the original value
reset_cnt recorded by the driver.
