ASoC: qcom: qdsp6v2: fix crash due to asynchronous read/write

Whenever an async read command is issued to dsp when
the driver is not enabled, there is a crash in userspace.
The read command is disallowed in the driver and an error
is propagated to userspace which results in the crash.
The driver is re-enabled in a subsequent asynchronous write
command anyway, so the async read command can be allowed.
Ensure that read is allowed by removing a superfluous check.
