nfsd: check nfsd4_acl_to_attr() return value in nfsd4_create()

Browse source

nfsd4_create() stores the return value of nfsd4_acl_to_attr() in
status, but the switch(create->cr_type) block unconditionally
overwrites it in every branch. ACL translation errors are silently
discarded, and the CREATE proceeds without the requested ACL.

Add an early exit check after nfsd4_acl_to_attr(), matching the
pattern already used in nfsd4_setattr().
