mb/siemens/mc_bdx1: Avoid dereferencing a NULL pointer

Coverity scan has found an error where a NULL pointer is dereferenced.
The bug would happen if the devicetree does not contain a valid entry
for PCA9538. In this case the code
 * if (dev->path.i2c.device == PCA9538_SLAVE_ADR)
would dereference to a NULL pointer.

This patch fixes this issue. Thanks coverity!
