A failure in the get_txreq() inline will result in a
slow path retry using __get_txreq().
__get_txreq() attempts to procure the qp s_lock, which
is already held in all callers.
Fix by deleting the s_lock maintenance in __get_txreq()
and add sparse syntax hooks to future proof the code.

Swapping a cable from a "Mgmt Allowed=No" switch port to a
"Mgmt Allowed=Yes" switch port doesn't send a pkey change
notification. Therefore, the link doesn't become active as
the oib_utils layer uses an old pkey table cache.
Fix by ensuring the pkey change notification is sent when
the table is changed both explicitly by the FM and implicitly
by the driver via a cable swap.

FULL_MGMT_P_KEY doesn't get cleared from the pkey table at link bounce
because the link down and link bounce code paths are different when
moving a QSFP cable on a switch. This causes an HFI unit connected to a
switch to try to be initialized to an FM node when the QSFP cable is
moved from a MgmtAllowed=NO port to a MgmtAllowed=YES port and back to a
MgmtAllowed=NO port. Remove FULL_MGMT_P_KEY from pkey table at link up.
