If the test fails because the expected value doesn't match, it's
useful to know what value was actually printed.

V3:
	- Include expected error check in gen_report()
	- Implement Drew's suggestion on cleaning up the function a bit
	- Update patch to use __base_sbi_ecall()
V2:
	- Reduce subject to fit 70 chars
	- Use report_info() to output expected vs received values,
	  leaving only necessary information for parsers on report()
