[media] m5mols: Improve the interrupt handling routines
The work struct based interrupt handling is not flexible enough
as the M-5MOLS control sequence involves I2C access sequences
before and after an interrupt is generated. A single waitqueue is
enough for the job so remove the work struct based code.
