io_uring: defer alloc_hint update to io_file_bitmap_set()
io_file_bitmap_get() returns a free bitmap slot, but if it isn't
used later, such as io_queue_rsrc_removal() returns error, in this
case, we should not update alloc_hint at all, which still should
be considered as a valid candidate for next io_file_bitmap_get()
calls.
To fix this issue, only update alloc_hint in io_file_bitmap_set().
