gpu: nvgpu: fix unsigned int declaration

In gr_gk20a_init_access_map(), we declare num_entries as "unsigned int"
But this variable is implicitly type casted into "int" while calling subsequent
functions

Hence explicitly declare it as type "int"

Also declare variable "w" as "int" too since we use it to compare against
num_entries

Jira NVGPU-446
