memtrace mmap issue has an out of bounds issue. This patch fixes the by
checking that the requested mapping region size should stay within the
allocated region size.

Fixes: 08a022ad3dfa ("powerpc/powernv/memtrace: Allow mmaping trace b
The user space calls mmap() to map VAS window paste address
and the kernel returns the complete mapped page for each
window. So return -EINVAL if non-zero is passed for offset
parameter to mmap().
See Documentation/arch/powerpc/vas-api.rst for mmap()
restrictions.
