[PATCH master] usb: typec: fix freeing uninitialized memory

[Ahmad Fatoum]

When the code was first added, a kzalloc was allocating the memory for
the struct device. This has been recently changed to malloc as a
shifting of the header caused the function to be no longer defined.

malloc() doesn't zero the memory though, leading to a potential freeing
of uninitialized memory in dev_set_name.

Fix this by using calloc() instead. Reintroducing kzalloc() would be
fine too, but calloc() saves some space, because it guarantees a smaller
alignment.
