s3:smbd: improve writecache profiling

In order to have useful profiling counters should never be decremented.
We need a separate counter for deallocation events.

The current value can be calculated by allocations - deallocations.

We also use better names and avoid having an array for the flush reasons.
This will simplify further profiling improvements a lot.

The value writecache_num_write_caches (this was similar to writecache_allocations)
is replaced by writecache_cached_writes, which counts the amount of writes which
were completely handled by the cache.
