Filipe Manana 2a39e59802 Btrfs: shrink further sizeof(struct extent_buffer)
The map_start and map_len fields aren't used anywhere, so just remove
them. On a x86_64 system, this reduced sizeof(struct extent_buffer)
from 296 bytes to 280 bytes, and therefore 14 extent_buffer structs can
now fit into a page instead of 13.
