Hello build bot (Jenkins), Jason Glenesk, Raul Rangel, Marshall Dawson,

soc/amd/common/lpc/espi_util: handle espi_get_configuration error

In espi_wait_channel_ready the return value of espi_get_configuration
didn't get checked before. In the case of the espi_send_command call in
espi_get_configuration returning CB_ERR, espi_get_configuration didn't
write to the local config variable, so if this happens in the first pass
of the do-while loop, the following espi_slave_is_channel_ready call
would use the uninitialized local config variable as parameter. Fix this
by checking the return value of espi_get_configuration.

TEST=None
