ALSA: pcm: use snd_pcm_get_state() in remaining ioctl checks

Browse source

The recent OSS runtime->state locking cleanup converted the OSS I/O
paths to use snd_pcm_get_state(), but a few ioctl-side checks in
pcm_native.c still sample runtime->state directly: the prepare
pre-checks, the early drain open-state check, and the common
snd_pcm_kernel_ioctl() disconnected check.

Use snd_pcm_get_state() for those remaining samples. In
snd_pcm_pre_prepare(), keep a single state snapshot and reuse it for
both the OPEN/DISCONNECTED check and the running-state test.
