offset: usize,
len: usize,

Enqueues a command to map a region of the buffer object given
by buffer
into the host address space and returns a pointer to this
mapped region.
Safety
Caller must ensure that the returned pointer is not used until the map is
complete. Use new_event
to monitor it. [TEMPORARY] It also must be
ensured that memory referred to by the returned pointer is not dropped,
reused, or otherwise interfered with until enqueue_unmap_mem_object
is
called.
TODO: Return a new wrapped type representing the newly mapped memory.
