Updated micscif/miscif_api.c for new get_user_pages() function.

At some point the function prototype changed from this:

    long get_user_pages(struct task_struct *tsk, struct mm_struct *mm,
                unsigned long start, unsigned long nr_pages,
                int write, int force, struct page **pages,
                struct vm_area_struct **vmas);

into this:

    long get_user_pages(unsigned long start, unsigned long nr_pages,
                    unsigned int gup_flags, struct page **pages,
                    struct vm_area_struct **vmas);

With the individual 'write' and 'force' flags transforming into gup_flags per

Updated host/vhost/mic_blk.c, adding a `MIC_` prefix to the SECTOR_SHIFT and
SECTOR_SIZE macros since there is a conflicting definition in
`/usr/src/linux-headers-4.19.0-16-common/include/linux/blkdev.h`.

The definitions are nearly identical and that in host/vhost/mic_blk.c could
probably be removed instead of prefixed. I'm just being conservative since I'm
making a bunch of changes at once without the ability to build and test along
the way.

Minor formatting changes in host/vhost/vhost.h.

Updated host/vhost/mic_vhost.c and vhost.h references from wait_queue_t to wait_queue_entry_t.
