osdep: fix qemu_anon_ram_free trace (+ fix compilation on 32 bit hosts)

Commit e7a09b92b70786f9e8c5fbf787e0248c6ebbe707 added a trace at each
memory freeing, but unfortunately inverted size and pointer when printing
them. Fix trace.

This also led to a compilation error on 32 bit hosts:
In file included from include/trace.h:4:0,
                 from trace/generated-events.c:3:
./trace/generated-tracers.h: In function ‘trace_qemu_anon_ram_free’:
./trace/generated-tracers.h:64:9: error: format ‘%zu’ expects argument of type
‘size_t’, but argument 3 has type ‘void *’ [-Werror=format]
./trace/generated-tracers.h:64:9: error: format ‘%p’ expects argument of type
‘void *’, but argument 4 has type ‘size_t’ [-Werror=format]
