P2P: Fix preferred frequency list size handling in p2p_check_pref_chan()

Currently, the P2P GO (Group Owner) prefers the PCL (Preferred Channel
List) from the driver to select the operating channel for group
formation. However, wpa_supplicant is limiting the maximum allowed
channels to "num_pref_freq", even though the driver may return a longer
list.

To fix this, update the logic in p2p_check_pref_chan() to use
ARRAY_SIZE(p2p->pref_freq_list) when passing the size to
get_pref_freq_list(), and update p2p->num_pref_freq based on the value
returned by the driver function. This ensures the preferred frequency
list is sized correctly according to the driver response.
