Alban Bedel 57a01173d1 iio:st_sensors: Fix oops when probing SPI devices 
commit 8e71c04f86 upstream.

In SPI mode the transfer buffer is locked with a mutex. However this
mutex is only initilized after the probe, but some transfer needs to
be done in the probe.

To fix this bug we move the mutex initialization at the beginning of
the device probe.

[ luis: backported to 3.16:
  - use 'pdata' instead of 'press_data' in st_press_common_probe()
  - adjusted context ]
