Overload is_dev_mounted() function (#767842) 

Small optimisation which avoids constructing an extra BlockSpecial
object when determining if a btrfs member is mounted.  Rather than
extracting the name from the BlockSpecial object in
btrfs::get_mount_device() and re-constructing another BlockSpecial
object from that name in GParted_Core::is_dev_mounted(), pass the
BlockSpecial object directly.

Bug 767842 - File system usage missing when tools report alternate block
             device names
