[PATCH v2 1/2] btrfs: use true/false for boolean parameters in btrfs_{inc,dec}_ref

[Sun YangKai <sunk67188@gmail.com>]

Replace integer literals 0/1 with true/false when calling
btrfs_inc_ref() and btrfs_dec_ref() to make the code self-documenting
and avoid mixing bool/integer types.

No functional change intended.
