partitions: mac: fix handling of bogus partition table

In the Linux kernel, the following vulnerability has been resolved:

partitions: mac: fix handling of bogus partition table

Fix several issues in partition probing:

 - The bailout for a bad partoffset must use put_dev_sector(), since the
   preceding read_part_sector() succeeded.
 - If the partition table claims a silly sector size like 0xfff bytes
   (which results in partition table entries straddling sector boundaries),
   bail out instead of accessing out-of-bounds memory.
 - We must not assume that the partition table contains proper NUL
   termination - use strnlen() and strncmp() instead of strlen() and
   strcmp().
