Subject: [PATCH] Bluetooth: hci_qca: Replace open-coded msleep()

These three lines make up what msleep() already does, i.e. setting the
task to uninterruptible, sleeping for so many jiffies, and then
schedule() already puts the task state back to TASK_RUNNING when it
returns. Make things clearer by just calling msleep() instead.
