Victor Ding 6613f36a2f platform/chrome: cros_ec_typec: zero out stale pointers ...

[ Upstream commit 9a8aadcf0b ]

`cros_typec_get_switch_handles` allocates four pointers when obtaining
type-c switch handles. These pointers are all freed if failing to obtain
any of them; therefore, pointers in `port` become stale. The stale
pointers eventually cause use-after-free or double free in later code
paths. Zeroing out all pointer fields after freeing to eliminate these
stale pointers.

Fixes: 1a8912caba ("platform/chrome: cros_ec_typec: Get retimer handle")
