arch/topology: Fix variable naming to avoid shadowing

Using 'hw_pressure' for local variable name is confusing in regard to the
per-CPU 'hw_pressure' variable that uses the same name:

  include/linux/arch_topology.h:DECLARE_PER_CPU(unsigned long, hw_pressure);

... which puts it into a global scope for all code that includes
<linux/topology.h>, shadowing the local variable.

Rename it to avoid compiler confusion & Sparse warnings.
