fs: Fix to correct the mbcache entries counter
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.
