target/ppc: Fix return value in tcg radix mmu fault handler 

The mmu fault handler should return 0 if it was able to successfully
handle the fault and a positive value otherwise.

Currently the tcg radix mmu fault handler will return 1 after
successfully handling a fault in virtual mode. This is incorrect
so fix it so that it returns 0 in this case.

The handler already correctly returns 0 when a fault was handled
in real mode and 1 if an interrupt was generated.

Fixes: d5fee0bbe6 ("target/ppc: Implement ISA V3.00 radix page fault handler")
