block: take offset into account in blk_bvec_map_sg again

Browse Source 
The rebase of commit 09595e0c9d ("block: pass a phys_addr_t to
get_max_segment_size") lost adding the total to to the offset in
blk_bvec_map_sg.  Add it back.

Fixes: 09595e0c9d ("block: pass a phys_addr_t to get_max_segment_size")
