media: rc: fix kernel-doc parameter names

There are several parameters there that are named wrong, as
reported by those warnings:

	drivers/media/rc/ir-sharp-decoder.c:47: warning: No description found for parameter 'ev'
	drivers/media/rc/ir-sharp-decoder.c:47: warning: Excess function parameter 'duration' description in 'ir_sharp_decode'
