x86/mm: Change cpa_flush() to call flush_kernel_range() directly
The function cpa_flush() calls __flush_tlb_one_kernel() and
flush_tlb_all().
Replacing that with a call to flush_tlb_kernel_range() allows
cpa_flush() to make use of INVLPGB or RAR without any additional
changes.
Initialize invlpgb_count_max to 1, since flush_tlb_kernel_range()
can now be called before invlpgb_count_max has been initialized
to the value read from CPUID.
[riel: remove now unused __cpa_flush_tlb]
