eventpoll: add missing kernel-doc for @ctx function parameters

Add the missing kernel-doc comments to prevent kernel-doc build
warnings while building the documentation.

WARNING: fs/eventpoll.c:1684 function parameter 'ctx' not described in 'reverse_path_check'
WARNING: fs/eventpoll.c:2349 function parameter 'ctx' not described in 'ep_loop_check_proc'

Fixes: e09c77d94003 ("eventpoll: hoist CTL_ADD scratch state into struct ep_ctl_ctx")
