[AGIPD][CORRECT] FIX : Remove pc_bools flag condition from gain_correction

• gain_correction() function is not only doing PC gain corrections.
• Adding if any(agipd_corr.pc_bools): for executing gain_correction() doesn't make sense.

Description

Adding the conditional flag in the notebook is wrong and it can produce wrong data. And it adds to the mess of agipdlib.py non transparent correction functions.

This was lately added in the last release.
