ALSA: emu10k1: Fix emu1010 dock attach check
The emu1010_firmware_thread() checks the previous dock status, but a
wrong register is recorded as the last status when the dock is plugged
in. Usually this isn't a big issue since this value gets overwritten
by the next loop after one second. But when a dock is unplugged
immediately after plugging, it means essentially missing undock
handling.
This patch addresses it by remembering the correct register value.
