io_uring: define and set show_fdinfo only if procfs is enabled

Browse Source 
Follow the pattern used with other *_show_fdinfo functions and only
define and use io_uring_show_fdinfo and its helper functions if
CONFIG_PROC_FS is set.

Fixes: 87ce955b24 ("io_uring: add ->show_fdinfo() for the io_uring file descriptor")
