glusterd : volume profile command on one of the node crashes glusterd

When volume profile command is issued on one of the node glusterd
crashes. Its a race condition which may hit when profile command and
status command is being executed from node A and node B respectively.
While doing so event GD_OP_STATE_BRICK_OP_SENT/GD_OP_STATE_BRICK_COMMITTED
is being triggered. As handling of event is not thread safe, hence context
got modify and glusterd crashes.

With the fix now we are validating the context before using it.
