btrfs-progs: Sync code with kernel for BTRFS_MAX_INLINE_DATA_SIZE 

Do a cleanup. Also make it consistent with kernel.  Use fs_info instead
of root for BTRFS_MAX_INLINE_DATA_SIZE, since maybe in some situation we
do not know root, but just know fs_info.

Change macro to inline function to be consistent with kernel.  And
change the function body to match kernel.
