Fix garbage handling in DMI strings.

Previously we tried to replace garbage characters with <space> directly in
the read-only memory-mapped SMBIOS area(!). This could never have
worked for any DMI strings with garbage and results in a segfault on
machines with such strings.

Thanks to Brian Rak (Supermicro X10SLE-F) and John Pohlman (HP XW9400)
for reporting this issue.

With this patch the strings are duplicated within dmi_string() already,
just before we sanitize them. Also, the limit variable used everywhere
points to the first invalid byte address. Refine respective checks
accordingly.

Improve messages on failed erases with default verbosity.

Without this...
Erasing and writing flash chip... ERASE FAILED at 0x00001000! Expected=0xff, Read=0xb4, failed byte count from 0x00000000-0x0000ffff: 0xef09
ERASE FAILED!
Reading current flash chip contents... done.
<loooooong break while the next eraser and writing is tried>
Erase/write done.
Verifying flash... VERIFIED.

Even if there is not a long temporal pause, it is very confusing for
the user to first see a failed erase, followed by a read, a done
message and eventually the verification message.
This patch inserts "Looking for another erase function." where there is
just a silent pause above.
