btrfs: pass boolean literals as the last argument to inc_block_group_ro()

The last argument of inc_block_group_ro() is defined as a boolean, but
every caller is passing an integer literal, 0 or 1 for false and true
respectively. While this is not incorrect, as 0 and 1 are converted to
false and true, it's less readable and somewhat awkward since the
argument is defined as boolean. Replace 0 and 1 with false and true.
