nutdec: fix illegal count check in decode_main_header
The existing check has two problems: 1) i + count can overflow, so that the check '< 256' returns true. 2) In the (i == 'N') case occurs a j-- so that the loop runs once more. This can trigger the assertion 'nut->header_len[0] == 0' or cause segmentation faults or infinite hangs.
