iio: accel: mma9551_core: Prevent uninitialized variable in mma9551_read_status_word()
[ Upstream commit e56d2c34ce9dc122b1a618172ec0e05e50adb9e9 ]
Smatch Warns: drivers/iio/accel/mma9551_core.c:357
mma9551_read_status_word() error: uninitialized symbol 'v'.
When (offset >= 1 << 12) is true mma9551_transfer() will return -EINVAL
without 'v' being initialized, so check for the error and return.
Note: Not a bug as such because the caller checks return value and
doesn't not use this parameter in the problem case.
