New Cisco IB SRP targets use the Cisco OUI 00-1b-0d but still need the
Topspin workarounds.  Add this OUI to srp_target_is_topspin().
Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Wrap the checking for Mellanox and Topspin OUIs to decide whether to
use a workaround into helper functions.  This will make it cleaner to
add a new OUI to check (as we need to do now that some targets with a
Cisco OUI still need the Topspin workarounds).

If ib_mad_recv_done_handler() fails to allocate response, then it just
printed a warning and continued, which leads to an oops if the MAD is
being handled for a switch device, because the switch code uses
response without checking for NULL.  Fix this by bailing out of the
function if the allocation fails.

Now that ib_find_pkey() ignores the membership bit of P_Keys, there's no
need for ib_sa to look for both 0x7fff and 0xffff in a port's P_Key table.
Signed-off-by: NRoland Dreier <rolandd@cisco.com>

ib_find_pkey() is used as a replacement for ib_find_cached_pkey(), and
the original function ignored the membership bit when searching for a
P_Key, so ib_find_pkey() should ignore the bit too.

In particular, IPoIB turns on the P_Key membership bit of limited
membership P_Keys when creating a child interface and looks for the
full membership P_key.  This broke if a port was a partial member of a
partition when IPoIB switched from ib_find_cached_pkey() to
ib_find_pkey(), and this change fixes things again.

1. The only place that RTPRIO_TO_LOAD_WEIGHT() is used is in the call to
move_tasks() in the function active_load_balance() and its purpose here
is just to make sure that the load to be moved is big enough to ensure
that exactly one task is moved (if there's one available).  This can be
accomplished by using ULONG_MAX instead and this allows
RTPRIO_TO_LOAD_WEIGHT() to be deleted.

2. This, in turn, allows PRIO_TO_LOAD_WEIGHT() to be deleted.
