User space understands the ioctl BTRFS_IOC_DEV_REPLACE command status
using the struct btrfs_ioctl_dev_replace_args::result, and so userspace
initializes this to BTRFS_IOCTL_DEV_REPLACE_RESULT_NO_RESULT, so exclude
this value in checking for the error.

Replace start fails to report the appropriate error if balance is already
running, as below,
btrfs rep start -B -f /dev/sdb /dev/sde /btrfs
ERROR: ioctl(DEV_REPLACE_START) on '/btrfs' returns error: <illegal
result value>
Fix it by checking if the return is > 0, as the kernel returns
BTRFS_ERROR_DEV_EXCL_RUN_IN_PROGRESS for the above cli, if the balance is
running.
