[PATCH] selftests/fs/mount-notify: fix the indentation in the fsmount test

[Sasha Levin <sashal@kernel.org>]

A few lines in the fsmount test are indented with spaces instead of a
tab. That puts them deeper than the ASSERT_*() in front of them, which
ends in a for loop with an empty body, so clang warns:

  mount-notify_test.c:338:18: warning: for loop has empty body [-Wempty-body]

Indent them with tabs.

Found with clang 21; KernelCI's clang builds show the same warnings.
Amir's pending fanotify series moves this file to filesystems/fanotify/,
and its rename still applies on top of this.
