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 Signed-off-by: David Sterba <dsterba@suse.com>
