[PATCH 2/2] target/arm: Fix compile error. |

When I compile qemu with such as:
git clone https://git.qemu.org/git/qemu.git
cd qemu
git submodule init
git submodule update --recursive
./configure
make
There is error log:
/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;
^
cc1: all warnings being treated as errors
So, add an initiallization value for fn to fix this.
