Memory leak in the virtual device applesmc
Description of problem:
In the function _qdev_applesmc_isa_reset_, the device mallocs the _AppleSMCData_ but does not free them, causing a memory leak.
The following log reveals it:
```
==1029295==ERROR: LeakSanitizer: detected memory leaksDirect leak of 80 byte(s) in 2 object(s) allocated from:
#0 0x5574dc600a82 in __interceptor_calloc compiler-rt/lib/asan/asan_malloc_linux.cpp:138:3
#1 0x7f4919b22c50 in g_malloc0 (/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x5ec50)

#7 0x5574de3059b3 in device_reset_child_foreach qemu/hw/core/qdev.c:276:9
```
Steps to reproduce:
1. Build qemu with the sanitizer
2. Boot the Linux kernel with the above command line.
3. Stop the qemu process
