platform/x86: oxpec: Add a lower bounds check in oxp_psy_ext_set_prop()
The "val->intval" variable is an integer which comes from the user. This
code has an upper bounds check but the lower bounds check was
accidentally omitted. The write_to_ec() take a u8 value as a parameter
so negative values would be truncated to positive values in the 0-255
range.
Return -EINVAL if the user passes a negative value.
