[STABLE v5.15.y v2 6/9] eventpoll: drop vestigial __ prefix from ep_remove_{file,epi}()

[Lee Jones <lee@kernel.org>]

From: Christian Brauner <brauner@kernel.org>

[ Upstream commit 0feaf644f7180c4a91b6b405a881afbfd958f1cf ]

With __ep_remove() gone, the double-underscore on __ep_remove_file()
and __ep_remove_epi() no longer contrasts with a __-less parent and
just reads as noise. Rename both to ep_remove_file() and
ep_remove_epi(). No functional change.
