dmaengine: qcom: bam_dma: free interrupt before the clock in error path
The BAM interrupt is requested with a devres helper and so on error it's
freed after probe() returns. We disable the clock before freeing or
masking it so it may still fire and we may end up reading BAM registers
with clock disabled.
Stop using devres for interrupts as we free it in remove() manually
anyway. Add an appropriate label and free the interrupt before disabling
the clock in error path and in remove().
