fs: Fix mnt_count typo

Clark noticed the following snippit in commit
070976b5b038218900648ea4cc88786d5dfcd58d :

        if (mnt->mnt_pinned) {
-               inc_mnt_count(mnt);
+               preempt_disable();
+               dec_mnt_count(mnt);
+               preempt_enable();
                mnt->mnt_pinned--;
        }
        vfsmount_write_unlock();


I accidentally replaced an inc_mnt_count() with a dec_mnt_count().

The issue went unnoticed, as the only user of mnt_unpin in the acct
syscall.

This patch corrects the mistake.
