NFC: add NULL checks to avoid potential NULL pointer dereference

NULL checks at line 457: if (!link0 || !link1) {, implies that both
pointers link0 and link1 might be NULL.
Function nfcsim_link_free() dereference pointers link0 and link1.
Add NULL checks before calling nfcsim_link_free() to avoid a
potential NULL pointer dereference.
