nfsd: make sure to balance get/put_write_access
Use a straight goto error label style in nfsd_setattr to make sure we always do the put_write_access call after we got it earlier. Note that the we have been failing to do that in the case nfsd_break_lease() returns an error, a bug introduced into 2.6.38 with 6a76bebe "nfsd4: break lease on nfsd setattr".
