Swaraj Gaikwad 3f6cf0653f drm/msm: Replace custom dumb_map_offset with generic helper ...

The msm driver implements a custom dumb_map_offset callback. This
implementation acquires the msm_gem_lock, but the underlying
drm_gem_create_mmap_offset() function is already thread-safe regarding
the VMA offset manager (it acquires the mgr->vm_lock internally).

Switching to the generic drm_gem_dumb_map_offset() helper provides
several benefits:
1. Removes the unnecessary locking overhead (locking leftovers).
2. Adds a missing check to reject mapping of imported objects, which is
   invalid for dumb buffers.
3. Allows for the removal of the msm_gem_dumb_map_offset() wrapper and
   the msm_gem_mmap_offset() helper function.

The logic from msm_gem_mmap_offset() has been inlined into
msm_ioctl_gem_info() to maintain functionality without the separate
helper.

This addresses the TODO:
"Documentation/gpu/todo.rst: Remove custom dumb_map_offset implementations"
