NFS2: Calculate 'w' a bit later in nfsaclsvc_encode_getaclres()
This is a small performance optimization since we can return before
needing 'w'. It also saves a few bytes of .text :
Before:
text data bss dec hex filename
2406 212 0 2618 a3a fs/nfsd/nfs2acl.o
After:
text data bss dec hex filename
2400 212 0 2612 a34 fs/nfsd/nfs2acl.o
