ec/chromeec: fix LPC read/write for MEC devices
Commit 8cf8aa2 [ec/google/chromeec: Use common MEC interface] changed the return mechanism for the checksum on reads/writes for MEC devices, but incorrectly handled the passed-in csum parameter by not dereferencing. This led to the returned csum value always being zero, which causes all EC commands with non- NULL data_in to fail with a checksum error. Fix this by storing the returned checksum in a temp variable, and only assigning to csum when the pointer isn't NULL; Test: build/boot google/chell, verify EC hello command succeeds, keyboard backlight turned on at boot.
