mtdinfo: provide info when used without arguments
If the user specifies neither a MTD argument nor the `-a' flag, we print
a cryptic message; i.e.,
# mtdinfo
libmtd: error!: cannot get information about "(null)"
error 14 (Bad address)
mtdinfo: error!: cannot get information about MTD device "(null)"
error 14 (Bad address)
This is a regression; previously, mtdinfo would give some short info
about number of devices, etc. when used without arguments. To fix this,
we revert commit d53c03b0989f8354a7e4dbb947a150fc7fe3f6d1 and call
print_general_info() when no device is specified.
