Marek VasutandTom Rini 717f8ded39 boot: Check noffset before use
If noffset is negative, do not pass it to fit_get_name() and then further to
libfdt, this will crash sandbox with SIGSEGV because libfdt can not handle
negative node offsets without full tree check, which U-Boot inhibits to keep
size lower.

Instead, always check noffset before use, and if the return value indicates
failure, exit right away.
