[PATCH v3] nl80211: Driver capability retrieval only once the interface is UP

[Sreenath Sharma]

The main intention of this patch is to retrieve driver capabilities only
once the interface is UP, similar to the older approach before P2P_DEVICE
integration. This approach will help devices which can retrieve the
capabilities from firmware only once the interface is UP.

v3: Applied v2 changes on top of v1
v2: Fixed hostapd compilation issue

Please discard v2 and v1 patches.
