Thomas Bogendoerfer 841ecc979b MIPS: mm: kmalloc tlb_vpn array to avoid stack overflow 
Owing to Config4.MMUSizeExt and VTLB/FTLB MMU features later MIPSr2+
cores can have more than 64 TLB entries.  Therefore allocate an array
for uniquification instead of placing too an small array on the stack.

Fixes: 35ad7e1815 ("MIPS: mm: tlb-r4k: Uniquify TLB entries on init")
