ntfs3: add buffer boundary checks to run_unpack()

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

ntfs3: add buffer boundary checks to run_unpack()

run_unpack() checks `run_buf < run_last` at the top of the while loop
but then reads size_size and offset_size bytes via run_unpack_s64()
without verifying they fit within the remaining buffer.  A crafted NTFS
image with truncated run data in an MFT attribute triggers an OOB heap
read of up to 15 bytes when the filesystem is mounted.

Add boundary checks before each run_unpack_s64() call to ensure the
declared field size does not exceed the remaining buffer.

Found by fuzzing with a source-patched harness (LibAFL + QEMU).
