[PATCH] ipa: rpi: Prevent segfault if AGC algorithm is absent

[Benjamin Mugnier]

Even without AGC definition in the tuning file, the application would
still dereference agc unconditionally, leading to a segmentation fault
if AGC is absent.
This is relevant for sensors already providing AGC/AEC by themselves.
Check if AGC is present prior to setting maximum exposure time.
