Fix incorrect error handling in afs_xattr_get_acl() where there appears to
be a redundant assignment before return, but in fact the return should be a
goto to the error handling at the end of the function.

Fixes: 260f082bae6d ("afs: Get an AFS3 ACL as an xattr")
Addresses-Coverity: ("Unused Value")
