i2c: mxs: Fix type of error code
commit 0f40cbc4f85e13b1a42ae2f41231645a14965872 upstream.
cmd_err is used to handle error code, so it should not be unsigned.
This fixes the following warning when building with W=1 option:
drivers/i2c/busses/i2c-mxs.c: In function 'mxs_i2c_xfer_msg':
drivers/i2c/busses/i2c-mxs.c:331:19: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
