fsmonitor: trace the new invalidated cache-entry count

Consolidate the directory/non-directory calls to the refresh handler
code.  Log the resulting count of invalidated cache-entries.

The nr_in_cone value will be used in a later commit to decide if
we also need to try to do case-insensitive lookups.
