Subject: fs: fix to correct the mbcache entries counter
From: "Ram Gupta" <ram.gupta5@xxxxxxxxx>
This patch fixes the c_entry_count counter of the mbcache. Currently it
increments the counter first & allocate the cache entry later. In case of
failure to allocate the entry due to insufficient memory this counter is
still left incremented. This patch fixes this anomaly.
