firmware_loader: Expand Firmware upload error codes with firmware invalid error
No error code are available to signal an invalid firmware content.
Drivers that can check the firmware content validity can not return this
specific failure to the user-space
Expand the firmware error code with an additional code:
- "firmware invalid" code which can be used when the provided firmware
is invalid
Sync lib/test_firmware.c file accordingly.
