btrfs-progs: Introduce device delete by devid
This patch introduces new option <devid> for the command
btrfs device delete <device_path|devid>[..] <mnt>
In a user reported issue on a 3-disk-RAID1, one disk failed with its
SB unreadable. Now with this patch user will have a choice to delete
the device using devid.
The other method we could do, is to match the input device_path
to the available device_paths with in the kernel. But that won't
work in all the cases, like what if user provided mapper path
when the path within the kernel is a non-mapper path.
This patch depends on the below kernel patch for the new feature to work,
however it will fail-back to the old interface for the kernel without the
patch
