sys/vfs/hammer2: Cleanup freemap index calculation

Freemap bitmaps (64KB x 5levels x 8rotations) exist in the first
4MB area of every 1GB, so bitmap offset mask should be 4MB-1 rather
than 1GB-1. It explicitly wants to clear bit 22-29.

This doesn't change the result since bref->data_off for freemap
itself has to have 0 for bit 22-29.
