[PATCH liburing v1 2/5] register: Remove useless branches in {un,}register buffers

[Ammar Faizi <ammarfaizi2@gnuweeb.org>]

From: Ammar Faizi <ammarfaizi2@gnuweeb.org>

IORING_REGISTER_BUFFERS and IORING_UNREGISTER_BUFFERS don't return a
positive value. These bracnes are useless. Remove them.

[1]: io_sqe_buffers_register
[2]: io_sqe_buffers_unregister
