ARCH: AUDIT: audit_syscall_entry() should not require the arch

Browse Source 
We have a function where the arch can be queried, syscall_get_arch().
So rather than have every single piece of arch specific code use and/or
duplicate syscall_get_arch(), just have the audit code use the
syscall_get_arch() code.
