UBI: fix warnings when debugging is enabled
The 'ubi_io_read_vid_hdr()' and 'ubi_io_read_ec_hdr()' function have the 'verbose' argument which controls whether they should print a warning if the VID/EC header was not found or was corrupted. Some callers require the headers to be OK, and pass 1. Some allow a corrupted/not present header, and pass 0. if (UBI_IO_DEBUG) verbose = 1; And UBI_IO_DEBUG is 1 if CONFIG_MTD_UBI_DEBUG_MSG_BLD is true. So in this case the warning is printed all the time. This confuses people. Thus, do not print the messages as warnings if UBI_IO_DEBUG is true, but print them as debugging messages instead.
