Subject: [PATCH 2/2] android: binder: add missing return value documentation for binder_apply_fd_fixups()

The kernel-doc for binder_apply_fd_fixups() was missing a description of
its return value, which triggers a kernel-doc warning.

Add the missing "Return:" entry to doc that the function returns 0 on
success or a negative errno on failure.
