io_uring: avoid ring quiesce while registering restrictions and enabling rings

IORING_SETUP_R_DISABLED prevents submitting requests and so there will be
no requests until IORING_REGISTER_ENABLE_RINGS is called. And
IORING_REGISTER_RESTRICTIONS works only before
IORING_REGISTER_ENABLE_RINGS is called. Hence ring quiesce is not needed
for these opcodes.
