V4L/DVB (8252): buf-dma-sg.c: avoid clearing memory twice

1) Remove a useless initialisation of 'i'

2) Avoid clearing the memory allocated twice (once in 'kcalloc', once
   in 'sg_init_table')

3) Remove a test that can never trigger.  The function returns NULL in
   such a case, so we know that at this point 'pages[0]' != NULL

The tvaudio driver is using "official" I2C device IDs for internal

it shouldn't do that. As the stored values are never used, the easiest
way to fix the problem is simply to remove them altogether.
