gstrtspsrc: 551 should not result in an unhandled error

Browse source 
Some cameras (e.g. HikVision DS-2CD2732F-IS) return "551 Option
not supported" when a command is sent that is not implemented
(e.g. PAUSE). Instead; it should return "501 Not Implemented".

This is wrong, as previously, the camera did announce support for PAUSE
in the OPTIONS.

In this case, handle the 551 as if it was 501 to avoid throwing errors
to application level. */
