IB/core: Fix memory corruption in ib_cache_gid_set_default_gid

Browse source

When ib_cache_gid_set_default_gid is called from several threads,
updating the table could make find_gid fail, therefore a negative
index will be retruned and an invalid table entry will be used.
Locking find_gid as well fixes this problem.
