mt7915_coredump_build()/mt7996_coredump_build() wrote dump_mem->len
unconditionally, but the allocation only reserves room for the memory
dump header when coredump_memdump is enabled and memdump_buf_len is
non-zero. In the default configuration the allocation ends right after
the fixed header, so the write landed one struct past the buffer. Only
populate the memory-dump section when it was actually allocated.
