H A Dvsprintf.cf97ca2c8 Mon May 18 14:07:07 CDT 2020 Arvind Sankar <nivedita@alum.mit.edu> efi/printf: Abort on invalid format

If we get an invalid conversion specifier, bail out instead of trying to
fix it up. The format string likely has a typo or assumed we support
something that we don't, in either case the remaining arguments won't
match up with the remaining format string.
