[PATCH v5 10/22] media: rzg2l-cru: Remove unnecessary WARN_ON check in format func

`WARN_ON(!fmt)` check in `rzg2l_cru_format_bytesperline()` is unnecessary
because the `rzg2l_cru_format_align()` function ensures that a valid
`pixelformat` is set before calling `rzg2l_cru_format_bytesperline()`. As
a result, `rzg2l_cru_format_from_pixel()` is guaranteed to return a
non-NULL value, making the check redundant.

Additionally, the return type of `rzg2l_cru_format_bytesperline()` is
`u32`, but the code returned `-EINVAL`, a negative value. This mismatch is
now resolved by removing the invalid error return path.
