bd: Add BD support to other xlators
Make changes to distributed xlator to work with BD xlator. Unlike files, a block device can't be removed when its opened. So some part of the code were moved down to avoid this situation. Also before truncating a BD file its BD_XATTR should be set otherwise truncate will result in truncating posix file. So file is created with needed BD_XATTR and truncate is invoked. Also enables BD xlator in stripe volume type. Change-Id: If127516e261fac5fc5b137e7fe33e100bc92acc0 BUG: 1028672 Signed-off-by: M.
