[PATCH 1/2] bcachefs: split error messages of invalid compression into two lines

[Integral <integral@archlinuxcn.org>]

When an invalid compression type or level is passed as an argument
to `--compression`, two error messages are squashed into one line:

    > bcachefs format --compression=lzo bcachefs-comp.img
    invalid option: invalid compression typecompression: parse error

    > bcachefs format --compression=lz4:16 bcachefs-comp.img
    invalid option: invalid compression levelcompression: parse error

To resolve this issue, add a newline character at the end of the
first error message to separate them into two lines.
