Doug Ledford d29c9ab1a2 IB/core: Fix oops in ib_cache_gid_set_default_gid
When we fail to find the default gid index, we can't continue
processing in this routine or else we will pass a negative
index to later routines resulting in invalid memory access
attempts and a kernel oops.

Fixes: 03db3a2d81e6 (IB/core: Add RoCE GID table management)
