cbfs: Prevent overflow and infinite loop in cbfs_walk
CBFS file with lenth of (UINT32_MAX - cbfs_file.offset + 1) causes overflow, making cbfs_walk() being stuck in an infinite loop, and checking the same file. This patch makes cbfs_walk() skip file headers with incorrect data_offset or data_length.
