hw/mips: load_elf_strerror to report kernel loading failure

Emulated MIPS boards bail out with a simple "could not load kernel" when
a kernel could not be load, without specifying the underlying reason.
Fix that by calling load_elf_strerror.

At the same time use error_report to report the error instead of
fprintf.
