io_uring/register: drop redundant submitter_task check

For IORING_SETUP_SINGLE_ISSUER io_ring_ctx's, io_register_resize_rings()
checks that the current task is the ctx's submitter_task. However, its
caller __io_uring_register() already checks this. Drop the redundant
check in io_register_resize_rings().
