Windows: Apply MAX_FID_COUNT to AFS Redirector

Browse Source 
Provide consistency between the SMB path parser and the AFS
redirector path processing by using the same constant, MAX_FID_COUNT,
for both.  MAX_FID_COUNT is the maximum number of unique file ids
that can exist in a path after all mount points and symlinks have
been expanded.  The current value is 512.
