Subject: i40iw: Change mem_resources pointer to a u8

From: Shiraz Saleem <shiraz.saleem@intel.com>

commit 6c7d46fdb8165ece4b0a17fb8f0b9320dbfeffc2 upstream.

iwdev->mem_resources is incorrectly defined as an unsigned
long instead of u8. As a result, the offset into the dynamic
allocated structures in i40iw_initialize_hw_resources() is
incorrectly calculated and would lead to writing of memory
regions outside of the allocated buffer.

Fixes: 8e06af711bf2 ("i40iw: add main, hdr, status")
