The keep alive received counter is a software stat, keep it grouped with
all other software stats. Since all stored stats are software stats,
remove the efa_sw_stats struct and use efa_stats instead.

Like any other verbs objects, CQ shouldn't fail during destroy, but
mlx5_ib didn't follow this contract with mixed IB verbs objects with
DEVX. Such mix causes to the situation where FW and kernel are fully
interdependent on the reference counting of each side.
Kernel verbs and drivers that don't have DEVX flows shouldn't fail.

Like any other IB verbs objects, AH are refcounted by ib_core. The release
of those objects are controlled by ib_core with promise that AH destroy
can't fail.
Being SW object for now, this change makes dealloc_ah() to behave like any
other destroy IB flows.

The IB verbs objects are counted by the kernel and ib_core ensures that
deallocate PD will success so it will be called once all other objects
that depends on PD will be released. This is achieved by managing various
reference counters on such objects.
The mlx5 driver didn't follow this standard flow when allowed DEVX objects
that are not managed by ib_core to be interleaved with the ones under
ib_core responsibility.
In such interleaved scenarios deallocate command can fail and ib_core will
leave uobject in internal DB and attempt to clean it later to free
resources anyway.
This change partially restores returned value from dealloc_pd() for all
drivers, but keeping in mind that non-DEVX devices and kernel verbs paths
shouldn't fail.

Add a new stat that counts mmap failures, which might help when debugging

Following patch adds additional argument to the create AH function, so it
make sense to group ah_attr and flags arguments in struct.

There's no reason to separate the network attributes from all other
device attributes. Embed the fields inside the device attributes and
query them all in one function.
