NFSD: Fix crash in nfsd4_read_release()

Browse Source 
commit abb1f08a2121dd270193746e43b2a9373db9ad84 upstream.

When tracing is enabled, the trace_nfsd_read_done trace point
crashes during the pynfs read.testNoFh test.

Fixes: 15a8b55dbb ("nfsd: call op_release, even when op_func returns an error")
