Subject: [PATCH] alsactl: Fix double decrease of lock timeout
The state_lock() has a loop to wait for the lock file creation, and
the timeout value gets decremented twice mistakenly, which leads to a
half timeout (5 seconds) than expected 10 seconds. Fix it.

Subject: [PATCH] alsactl: Fix race at creating a lock file
A race at creating a lock file in state_lock() was discovered
recently: namely, between the first open(O_RDWR) and the second
open(O_RDWR|O_CREAT|O_EXCL) calls, another alsactl invocation may
already create a lock file, then the second open() will return EEXIST,
which isn't handled properly and treated as a fatal error.
In this patch, we check EEXIST case and try again open() with O_RDWR.
This must succeed usually, and if it fails, handle finally as the
fatal error.

Subject: [PATCH ] alsactl: Remove asound.state file check from alsa-restore.service again
We added the check of asound.state file presence some time ago to
assure that alsactl gets called only if the state file is already
present. Since then, the situation has changed significantly:
e.g. now alsactl does initialize if the state file isn't present, and
the same alsa-restore.service is used to save the state. This means
that we should start this service no matter the state file exists at
the boot time or not. So, revert the old change again.
