This patch changes the multi-block allocation code, such that
directory inodes only get a single block reserved in the bitmap.
That way, the bitmaps are more tightly packed together, and there
are fewer spans of free blocks for in-use block reservations.
This means it takes less time to find a free span of blocks in the
bitmap, which speeds things up. This increases the performance of
some workloads by almost 2X. In Nate's mockup.py script (which does
(1) create dir, (2) create dir in dir, (3) create file in that dir)
the test executes in 23 steps rather than 43 steps, a 47%
performance improvement.

Recent commit e61133dd added support
for a new firmware feature to force an adapter to use 32 bit MSIs.
However, this firmware is not available for all systems. The hack below
allows devices needing 32 bit MSIs to work on these systems as well.
It is careful to only enable this on Gen2 slots, which should limit
this to configurations where this hack is needed and tested to work.

Corner cases in the code prevent us from processing an entire

In function be_get_nic_desc(), it will go through the descriptor array
returned from f/w. By comparing the desc_type field, it determines whether
there is a nic descriptor in the array or not. In the case of no nic
descriptor, this function should return NULL.

The code may return an invalide descriptor, when there is no nic descriptor
in the array and the desc_count is less than MAX_RESOURCE_DESC. In this case,
even there is no nic descriptor, it will still return the lase descriptor
since the i doesn't equal to MAX_RESOURCE_DESC.

This patch fix this issue by returning the descriptor when find it and return
NULL for other cases.
