btrfs-progs: convert strerror to implicit %m

Similar to the changes where strerror(errno) was converted, continue
with the remaining cases where the argument was stored in another
variable.

The savings in object size are about 4500 bytes:

 $ size btrfs.old btrfs.new
   text    data     bss     dec     hex filename
 805055   24248   19748  849051   cf49b btrfs.old
 804527   24248   19748  848523   cf28b btrfs.new
