i40iw: Change mem_resources pointer to a u8 

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: 8e06af711b ("i40iw: add main, hdr, status")
