[igt-dev] [PATCH i-g-t] tests/gem_fd_exhaustion: Remove broken exit handler

[Arkadiusz Hiler]

With the introduction of igt_allow_unlimited_files() the way the
original implementation that set RLIMIT_NOFILE and then restored it got
half-removed.

The new way of setting was used, but the old exit handler was still in place,
resetting the value to uninitialized variable.

Since we seem to not care about restoring the original limit in multiple
other places let's not do that here and instead ponder on doing that
elsewhere.

Fixes: 8bc80862603b ("lib: add igt_allow_unlimited_files()")
