[PULL 84/87] hw/ppc/spapr_numa.c: simplify spapr_numa_write_assoc_lookup_arrays()

[Cédric Le Goater]

From: Daniel Henrique Barboza <danielhb413@gmail.com>

We can get the job done in spapr_numa_write_assoc_lookup_arrays() a bit
cleaner:

- 'cur_index = int_buf = g_malloc0(..)' is doing a g_malloc0() in the
'int_buf' pointer and making 'cur_index' point to 'int_buf' all in a
single line. No problem with that, but splitting into 2 lines is clearer
to follow

- use g_autofree in 'int_buf' to avoid a g_free() call later on

- 'buf_len' is only being used to store the size of 'int_buf' malloc.
Remove the var and just use the value in g_malloc0() directly

- remove the 'ret' var and just return the result of fdt_setprop()
