dma mapping : export caller to vmallocinfo
For example on arm64 board, this add info to "user" entries in vmallocinfo
Before :
[...]
0xffffff8008997000 0xffffff80089d8000 266240 user
[...]
Afer :
[...]
0xffffff8008997000 0xffffff80089d8000 266240 atomic_pool_init+0x0/0x1d8 user
[...]
This help to debug mapping issues, and is consistent with others entries
(ioremap, vmalloc, ...) that already provide caller.
