Subject: [PATCH 5.10 03/95] io_uring: fix splice_fd_in checks backport typo

From: Kamal Mostafa <kamal@...onical.com>

The linux-5.10.y backport of commit "io_uring: add ->splice_fd_in checks"
includes a typo: "|" where "||" should be. (The original upstream commit
is fine.)

Fixes: 54eb6211b979 ("io_uring: add ->splice_fd_in checks")
