From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently when an alloc_page fails the error return is not set in
variable err and a garbage initialized value is returned. Fix this
by setting err to -ENOMEM before taking the error return path.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: a1f26739ccdc ("NFSv4.2: improve page handling for GETXATTR")
