media: i2c: ov9282: restore flash duration calculation

Browse Source 
The migration to CCI helpers made V4L2_CID_FLASH_DURATION write the
requested duration directly to OV9282_REG_STROBE_FRAME_SPAN, dropping
the conversion from microseconds to the register value.

This made flash strobes too long and produced overly bright frames.
Restore the missing calculation so flash duration is programmed
correctly again.
