sandbox: cros_ec: fix uninitialized use of len
Building with gcc-5.2 raises this warning:
drivers/misc/cros_ec_sandbox.c: In function cros_ec_sandbox_packet:
drivers/misc/cros_ec_sandbox.c:483:5: warning: len may be used uninitialized in this function [-Wmaybe-uninitialized]
if (len < 0)
^
If the function process_cmd() is called with
req_hdr->command == EC_CMD_ENTERING_MODE, the value of len will be
returned uninitialized.
