btrfs: Refactor __get_raid_index() to btrfs_bg_flags_to_raid_index()
Function __get_raid_index() is used to convert block group flags into
raid index, which can be used to get various info directly from
btrfs_raid_array[].
Refactor this function a little:
1) Rename to btrfs_bg_flags_to_raid_index()
Double underline prefix is normally for internal functions, while the
function is used by both extent-tree and volumes.
Although the name is a little longer, but it should explain its usage
quite well.
2) Move it to volumes.h and make it static inline
Just several if-else branches, really no need to define it as a normal
function.
This also makes later code re-use between kernel and btrfs-progs
easier.
3) Remove function get_block_group_index()
Really no need to do such a simple thing as an exported function.
