target/arm: Avoid maybe-uninitialized warning with gcc 4.9
GCC version 4.9.4 isn't clever enough to figure out that all execution paths in disas_ldst() that use 'fn' will have initialized it first, and so it warns: /home/LiKaige/qemu/target/arm/translate-a64.c: In function ‘disas_ldst’: /home/LiKaige/qemu/target/arm/translate-a64.c:3392:5: error: ‘fn’ may be used uninitialized in this function [-Werror=maybe-uninitialized] fn(cpu_reg(s, rt), clean_addr, tcg_rs, get_mem_index(s), ^ /home/LiKaige/qemu/target/arm/translate-a64.c:3318:22: note: ‘fn’ was declared here AtomicThreeOpFn *fn; ^ Make it happy by initializing the variable to NULL.
