Andreas Gruenbacher f794c839df gfs2: Fix error handling in init_statfs 
commit 5d49d3508b3c67201bd3e1bf7f4ef049111b7051 upstream.

On an error path, init_statfs calls iput(pn) after pn has already been put.
Fix that by setting pn to NULL after the initial iput.

Fixes: 97fd734ba17e ("gfs2: lookup local statfs inodes prior to journal recovery")
