[PATCH 2/3] ipc/mach_debug.c (host_ipc_hash_info): quiet GCC warning about uninitialized variable

[Marin Ramesa]

Don't initialize to zero, rather move the initialization of size before
the break statement. Break on the first iteration should never happen, so the
position of initialization doesn't matter.

* ipc/mach_debug.c (host_ipc_hash_info) (size): Don't initialize to zero.
(host_ipc_hash_info) (size): Move initialization before the break statement.
