msm: qmi: Update the wait-for-response to UNINTERRUPTIBLE

Currently once a QMI request is sent, the wait for the response is
interruptible. Sometimes the wait returns -ERESTARTSYS due to signals or
for reasons other than response reception. Since the interface to send
a QMI request is restricted completely within the kernel-space, the
kernel QMI client is not able to handle -ERESTARTSYS gracefully.

Update the wait-for-response in the interface API to uninterruptible.
