cros_ec: fix nul-termination for firmware build info
[ Upstream commit 50a0d71a5d20e1d3eff1d974fdc8559ad6d74892 ]
As gcc-8 reports, we zero out the wrong byte:
drivers/platform/chrome/cros_ec_sysfs.c: In function 'show_ec_version':
drivers/platform/chrome/cros_ec_sysfs.c:190:12: error: array subscript 4294967295 is above array bounds of 'uint8_t[]' [-Werror=array-bounds]
This changes the code back to what it did before changing to a
zero-length array structure.
Fixes: a841178445bb ("mfd: cros_ec: Use a zero-length array for command data")
