P2PS: Fix p2p_find last parameter handling

Browse source 
In p2p_find command line processing a loop searching for multiple
'seek=' parameters modifies cmd buffer adding '\0' terminators.
The 'freq=' parameter is handled after that and can be
lost if a 'freq=' follows 'seek=' in a command line.
Fix it by moving a handling of 'freq=' parameter to be processed
before 'seek=' handling loop.
