io_uring/rsrc: rename io_buffer_register_bvec()/io_buffer_unregister_bvec()
Currently, io_buffer_register_bvec() takes in a request. In preparation
for supporting kernel-populated buffers in fuse io-uring (which will
need to register bvecs directly, not through a struct request), rename
this to io_buffer_register_request().
A subsequent patch will commandeer the "io_buffer_register_bvec()"
function name to support registering bvecs directly.
Rename io_buffer_unregister_bvec() to a more generic name,
io_buffer_unregister(), as both io_buffer_register_request() and
io_buffer_register_bvec() callers will use it for unregistration.
