libdvbv5/dvb-scan-table-handler: remove free of unallocated structs

While those old structs are still part of struct dvb_v5_descriptors,
they are not allocated anymore. So, we don't need to fix them. Get
rid of those structs.

We can't remove them from the main struct yet, as dvb-file and
dvbv5-scan still use.

libdvbv5/dvb-scan: fix memory leak

As pointed by Valgrind, there are still some memory leaks at
dvb_get_ts_tables().

That happens because pmt is allocated by dvb_read_section().
Fix it.

While here, fix the error condition to not mangle with the main
dvb_scan_handler->program pointer.

libdvbv5: avoid playing with memory

Instead of reallocating the memory size for every single table,
just use the known size of the structure, as this is fixed.

The pat table here is an special case, due to the way its struct
is mapped. It is probably a good idea to use malloc there for the
struct dvb_table_pat_program program, but this would break compatibility
with libdvbv5 apps. So, let's keep it as-is.
