codecparser: h265: Fix nal unit size checking

Browse source 
The EOS and EOB nals have the size 2 which is the size of
nal unit header itself. The gst_h265_parser_identify_nalu()
is not required to scan start code again in this case.

In other cases, for a valid nalunit the minimum required size
is 3 bytes (2 byte header and at least 1 byte RBSP payload)
