Message:

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.
