Replaced the misleading uses of a historical artefact M_TRYWAIT with M_WAIT.
Removed dead code that assumed that M_TRYWAIT can return NULL; it's not true since the advent of MBUMA. Reviewed by: arch There are ongoing disputes as to whether we want to switch to directly using UMA flags M_WAITOK/M_NOWAIT for mbuf(9) allocation.
