dm: avoid NULL dereference in add_item()
acpi_add_other_item() passes dev = NULL. Instead of dev->name write the
string "other" to the debug log:
ACPI: Writing ACPI tables at 1fd3000
0base: writing table '<NULL>'
* other: Added type 3, 0000000011fd4000, size 240
1facs: writing table 'FACS'
* other: Added type 3, 0000000011fd4240, size 40
5csrt: writing table 'CSRT'
* other: Added type 3, 0000000011fd4280, size 30
