[PATCH] coverity: fs/locks.c flp null check

Browse Source 
We're dereferencing `flp' and then we're testing it for NULLness.

Either the compiler accidentally saved us or the existing null-pointer checdk
is redundant.

This defect was found automatically by Coverity Prevent, a static analysis tool.
