Subject: [PATCH -next] btrfs: Remove the unused function scrub_calc_parity_bitmap_len()

bitmap_len = scrub_calc_parity_bitmap_len(), the only call point of this
function has been deleted, so it should also be removed.

Fix the following W=1 kernel warning:
fs/btrfs/scrub.c:2857:19: warning: unused function 'scrub_calc_parity_bitmap_len'
