libmsc/ran_msg_a.c: avoid ternary operator in struct initialization

For some reason, having ternary operator there makes Coverity think
that 'n->geran.chosen_encryption' is dereferenced before checking
against NULL. Let's make it happy, and move the assignment.

Fixes: CID#198454 Dereference before null check
