[VFATFS] FATGetNextDirEntry(): Fix 1 MSVC 'warning C4267' (#6179)

Browse source 
Fix `warning C4267: '=': conversion from 'size_t' to 'USHORT', possible loss of data`
by explicitly casting to USHORT.
This is OK as the line immediately before NULL-terminates the buffer within boundary.

Addendum to commit 096a69471 (r6279).
