qcacmn: Remove lock free option in object manager iterate APIs

Object manager iterate APIs are provided with an option to decide
lock protection by the caller, as that is leading to race conditions
in SMP scenarios.

Locks are made default and handled possible deadlock scenarios,
handlers can take any object lock as required
