Subject: [PATCH (RESEND)] habanalabs: Fix test build failures

allmodconfig builds on 32-bit architectures fail with the following error.

drivers/misc/habanalabs/common/memory.c: In function 'alloc_device_memory':
drivers/misc/habanalabs/common/memory.c:153:49: error:
	cast from pointer to integer of different size

Add the missing typecast.

Fixes: e8458e20e0a3c ("habanalabs: make sure device mem alloc is page aligned")
