From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently when ns fails to be allocated the error return path returns
an uninitialized return code in variable 'err'. Fix this by setting
err to -ENOMEM.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 688330711e9a ("bcache: initialize the nvm pages allocator")
