ext4: fix oops in ext4_quota_off()

If quota is not enabled when ext4_quota_off() is called, we must not
dereference quota file inode since it is NULL. Check properly for
this.

This fixes a bug in commit 1603488f847f (ext4: remove unnecessary
[cm]time update of quota file), which was merged for 2.6.39-rc3.
