remoteproc: qcom: q6v5: Avoid disabling handover IRQ twice
enable_irq() and disable_irq() are reference counted, so we must make sure
that each enable_irq() is always paired with a single disable_irq(). If we
call disable_irq() twice followed by just a single enable_irq(), the IRQ
will remain disabled forever.
For the error handling path in qcom_q6v5_wait_for_start(), disable_irq()
will end up being called twice, because disable_irq() also happens in
qcom_q6v5_unprepare() when rolling back the call to qcom_q6v5_prepare().
Fix this by dropping disable_irq() in qcom_q6v5_wait_for_start(). Since
qcom_q6v5_prepare() is the function that calls enable_irq(), it makes more
sense to have the rollback handled always by qcom_q6v5_unprepare().
Fixes: 3b415c8fb263 ("remoteproc: q6v5: Extract common resource handling")
