btrfs_reserve_extent() uses int @data to determine if we're allocating
data extent, while reuse the parameter later to pass it as profile
(data/meta/sys).
It's a little confusing, this patch will follow kernel parameter to use
bool @is_data to replace it.
And in btrfs_reserve_extent(), use dedicated u64 @profile.
