i2c-eg20t : Fix the issue of Combined R/W transfer mode

Browse source 
issue-1
In case combined transfer mode fails halfway, the processing must be stopped halfway.
However currently, the processing is continued.
This patch breaks the processing.

issue-2
Currently, pch_i2c_xfer returns read/write size at that time.
However pch_i2c_xfer must return the number of messages to be read/written.
This patch modifies correctly.
