Carlos López baf6a75e3f lib: sbi: dbtr: fix potential NULL pointer dereferences ...

In several dbtr functions, we first check that the dbtr trigger is not
NULL and that its state is what we expect. However, it only makes
sense to perform the second check if the dbtr trigger is not NULL.
Othwerwise we will dereference a NULL pointer. Thus, change the
condition so that it shortcuts to the first check if necessary.
