[PATCH] coverity: sunrpc/xprt task null check

Browse Source 
In __xprt_lock_write() we check to see if `task' is NULL, but in other places
we just go and dereference it.

`task' shouldn't be NULL anyway, so remove this test.

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