x86/cpu: Simplify TLB entry count storage
Commit:
e0ba94f14f74 ("x86/tlb_info: get last level TLB entry number of CPU")
introduced u16 "info" arrays for each TLB type.
Since 2012 and each array stores just one type of information: the
number of TLB entries for its respective TLB type.
Replace such arrays with simple variables.
