[PATCH 2/3] mmc-utils: fix printing OID for mmc in non-verbose mode

[Enrico Jorns <ejo@pengutronix.de>]

It is parsed as an integer and printed as a char which does not really
make sense.
E.g. if OID is '0' (which does not seem to be uncommon), then this
prints a '\0' character and makes output nearly unreadable/unparsable.

Also, do not print it like it would be a string, instead use 0x<digit>
format.
