linuxkpi: Remove extraneous NULL check on M_WAITOK allocation
The check was not introduced in r342628, but the subsequent unchecked access to refs was added then, prompting a Coverity warning about "Null pointer dereferences (FORWARD_NULL)." The warning is bogus due to M_WAITOK, but so is the NULL check that hints it, so just remove it. CID: 1398588 Reported by: Coverity
