[PATCH] powerpc: Fix action argument for cpufeatures-based TLB flush

[Jeremy Kerr]

Commit 41d0c2ecde introduced calls to __flush_tlb_power[89] from the
cpufeatures code, specifying the number of sets to flush.

However, these functions take an action argument, not a number of sets.
This means we hit the BUG() in __flush_tlb_{206,300} when using
cpufeatures-style configuration.

This change passes TLB_INVAL_SCOPE_GLOBAL instead.
