This patch originates from the last comment of the following review:

https://lore.kernel.org/all/2df9ae98-afb8-4647-be80-12540a1c4612@ventanamicro.com/

We call probe_pages to probe the memory before doing a memory operations or
probe_access_flags to do the same while also obtaining probe flags and host
address.
This involves different calls to code that is almost the same.

This patch expands probe_pages to provide for both cases.

In the new version of probe_pages we don't have a return value to get the probe
flags. We need instead to pass a pointer to such variable in order to get the
flags.
