[media] af9015: Don't use dynamic static allocation

Browse Source 
Dynamic static allocation is evil, as Kernel stack is too low, and
compilation complains about it on some archs:
	drivers/media/usb/dvb-usb-v2/af9015.c:433:1: warning: 'af9015_eeprom_hash' uses dynamic stack allocation [enabled by default]
In this specific case, it is a gcc bug, as the size is a const, but
it is easy to just change it from const to a #define, getting rid of
the gcc warning.
