Subject: [PATCH RESEND] fs: Delete always true compilation define

From: Leon Romanovsky <leonro@...lanox.com>

In commit 1027abe8827b ("[PATCH] merge locate_fd() and get_unused_fd()")
the existing "#if 1" was moved from one place to another. Originally
that compilation define was set for the sanity check and more than 12
years later it is safe to remove it.
