MIPS: Fix write_gc0_* macros when writing zero
The versions of the __write_{32,64}bit_gc0_register() macros for when there is no virt support in the assembler use the "J" inline asm constraint to allow integer zero, but this needs to be accompanied by the "z" formatting string so that it turns into $0. Fix both macros to do this.
