x86/mm/pat: Fix W=1 build kernel-doc warning

Browse Source 
Building the kernel with W=1 generates the following warning:

  arch/x86/mm/pat/memtype.c:692: warning: Function parameter or struct member 'pfn' not described in 'pat_pfn_immune_to_uc_mtrr'

Add missing parameter documentation to fix the kernel-doc warning.
