Revert "mm: rename call_mmap/mmap_prepare to vfs_mmap/mmap_prepare"

JIRA: https://issues.redhat.com/browse/RHEL-113577
Upstream Status: RHEL only

This reverts commit 20ca475.

This commit was backported automatically as part of the DRM backport.

This tree still uses vfs_mmap() and mmap_prepare(). Use the previous
function names.

NOTE: This commit does not compile due to missing RHEL-specific fix-ups,
which are split out into separate Git commits following this one.

If git bisect selected this commit, run "git bisect skip" and try again.
Repeat this until it selects a commit which compiles.
