i2c: k1: check for transfer error
d7b5aab 
If spacemit_i2c_xfer_msg() times out waiting for a message transfer to
complete, or if the hardware reports an error, it returns a negative
error code (-ETIMEDOUT, -EAGAIN, -ENXIO. or -EIO).

The sole caller of spacemit_i2c_xfer_msg() is spacemit_i2c_xfer(),
which is the i2c_algorithm->xfer callback function.  It currently
does not save the value returned by spacemit_i2c_xfer_msg().

The result is that transfer errors go unreported, and a caller
has no indication anything is wrong.

When this code was out for review, the return value *was* checked
in early versions.  But for some reason, that assignment got dropped
between versions 5 and 6 of the series, perhaps related to reworking
the code to merge spacemit_i2c_xfer_core() into spacemit_i2c_xfer().

Simply assigning the value returned to "ret" fixes the problem.
