ACPI: APEI: GHES: Extract helper functions for error status handling
Refactors the GHES driver by extracting common functionality into
reusable helper functions:
1. ghes_has_active_errors() - Checks if any error sources in a given list
have active errors
2. ghes_map_error_status() - Maps error status address to virtual address
3. ghes_unmap_error_status() - Unmaps error status virtual address
4. Use `guard(rcu)()` instead of explicit `rcu_read_lock()`/`rcu_read_unlock()`.
These helpers eliminate code duplication in the NMI path and prepare for
similar usage in the SEA path in a subsequent patch.
No functional change intended.
