[PATCH] Patch for quota-tools to avoid project quota crash

[Theodore Ts'o <tytso@mit.edu>]

Hi Jan,

This patch is needed to avoid "quota -v -P 123" from crashing if
/etc/projid does not exist.

Cheers,

					- Ted

Subject: [PATCH] Don't crash if /etc/projid file does not exist

In endprent(), if project_file is NULL, don't try to fclose it, or
else glibc will not be amused.
