Revert "ptp: Fixes a null pointer dereference in ptp_ioctl"

Browse Source 
This reverts commit 8a4f030dbc.

Richard says:

  The test itself is harmless, but keeping it will make people think,
  "oh this pointer can be invalid."

  In fact the core stack ensures that ioctl() can't be invoked after
  release(), otherwise Bad Stuff happens.
