drivers: nrfx_{twi, twim}: Fix busy flag not reset

This is necessary so that next occurence of nrfx_{twi, twim}_enable() followed by {twi, twim}_xfer() will not raised a NRFX_ERROR_BUSY error. This could happen when a previous transfer is started but is aborted using nrfx_{twi, twim}_disable() before the end of the transaction which calls {twi, twim}_irq_handler().
