firmware: google memconsole: Fix return value check in platform_memconsole_init()
In case of error, the function platform_device_register_simple() returns
ERR_PTR() and never returns NULL. The NULL test in the return value
check should be replaced with IS_ERR().
Fixes: d384d6f43d1e ("firmware: google memconsole: Add coreboot support")
