msm: camera: common: Fix failures in v4l2 unregister during error

Missing video unregister was causing list delete corruption.
Also, there were double free errors in Sync and CRM driver. Fix
v4l2 issues by adding the missing unregister calls and changing
release callback to empty, because we are freeing it during
cleanup. Improve logging during bind/unbind to better reflect what
is happening.
