chromeec: fix an uninitialized local variable
google_chromeec_command() may only write the 1 or 2 bytes to
variable r (4 bytes). However, this api returns 4 bytes data.
To avaid returning the error data, we need to initialize the
local variable.
BUG=b:76442548
BRANCH=none
TEST=write 2 bytes data into the flash,
then, use cbi_get_uint32 read data back.
