IB/cm: Improve the calling of cm_init_av_for_lap and cm_init_av_by_path
The cm_init_av_for_lap() and cm_init_av_by_path() function calls have the
following issues:
1. Both of them might sleep and should not be called under spinlock.
2. The access of cm_id_priv->av should be under cm_id_priv->lock, which
means it can't be initialized directly.
This patch splits the calling of 2 functions into two parts: first one
initializes an AV outside of the spinlock, the second one copies AV to
cm_id_priv->av under spinlock.
