    scsi: ufs: mcq: Fix error output and clean up ufshcd_mcq_abort()
    
    [ Upstream commit d53b681ce9ca7db5ef4ecb8d2cf465ae4a031264 ]
    
    An error unrelated to ufshcd_try_to_abort_task is being logged and can
    cause confusion. Modify ufshcd_mcq_abort() to print the result of the abort
    failure. For readability, return immediately instead of 'goto'.
