drivers: qcom: ultrasound: Lock async driver calls

Adds lock to ioctl and other external calls to driver.
Adds missing null check in __usf_set_stream_param.

Conflicts:
    * usf_get_stream_param/usf_set_stream_param: patch was errorneously
      applied to the getter instead of the setter; manually fixed.
    * usf_compat_ioctl: Does not exist in our file; ignored.
    * usf_release: Context around lines for mutex unlock/destroy differ
      too much; manually added.
