drivers/virt/fsl_hypervisor: Fix error handling path
[ Upstream commit 7f360bec37857bfd5a48cef21d86f58a09a3df63 ]
First, when memory allocation for sg_list_unaligned failed, there
is a bug of calling put_pages() as we haven't pinned any pages.
Second, if get_user_pages_fast() failed we should unpin num_pinned
pages.
This will address both.
As part of these changes, minor update in documentation.
Fixes: 6db7199407ca ("drivers/virt: introduce Freescale hypervisor management driver")
