btrfs: do not subtract delalloc from avail bytes
The block group's avail bytes printed when dumping a space info subtract
the delalloc_bytes. However, as shown in btrfs_add_reserved_bytes() and
btrfs_free_reserved_bytes(), it is added or subtracted along with
"reserved" for the delalloc case, which means the "delalloc_bytes" is a
part of the "reserved" bytes. So, excluding it to calculate the avail space
counts delalloc_bytes twice, which can lead to an invalid result.
