[PATCH 1/2] rc-core: consistent use of rc_repeat()

[David Härdeman]

The NEC decoder and the Sanyo decoders check if dev->keypressed is true
before calling rc_repeat (without holding dev->keylock).

Meanwhile, the XMP and JVC decoders do no such checks.

This patch makes sure all users of rc_repeat() do so consistently by removing
extra checks in NEC/Sanyo and modifying the check a bit in rc_repeat() so that
no input event is generated if the key isn't pressed.
