usb: typec: intel_pmc_mux: Zero initialize num_ports in pmc_usb_probe()
Clang warns (or errors with CONFIG_WERROR=y / W=e):
drivers/usb/typec/mux/intel_pmc_mux.c:740:3: error: variable 'num_ports' is uninitialized when used here [-Werror,-Wuninitialized]
740 | num_ports++;
| ^~~~~~~~~
This should have been initialized to zero. Do so now to clean up the
warning and ensure num_ports does not use uninitialized memory.
Fixes: 8bdb0b3830ea ("usb: typec: intel_pmc_mux: combine kzalloc + kcalloc")
