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.
