MFC r365333:

  cam_sim: harmonize code related to acquiring a mtx

  cam_sim_free(), cam_sim_release(), and cam_sim_hold() all assign
  a mtx variable during declaration and then if NULL or the mtx is
  held may re-asign the variable and/or acquire/release a lock.

  Harmonize the code, avoiding double assignments and make it look
  the same for all three function (with cam_sim_free() not needing
  an extra case).

  No functional changes intended.
