NFC: Only warn on SE discovery error

SE discovery errors are currently overwriting the dev_up() return error.
This is wrong for many reasons:

- We don't want to report an error if we actually brought the device up
  but it failed to discover SEs. By doing so we pretend we don't have an
  NFC functional device even we do. The only thing we could not do was
  checking for SEs availability. This is the false negative case.

- In some cases the actual device power up failed but the SE discovery
  succeeded. Userspace then believes the device is up while it's not.
  This is the false positive case.

NFC: Fix target mode p2p link establishment

With commit e29a9e2ae165620d, we set the active_target pointer from
nfc_dep_link_is_up() in order to support the case where the target
detection and the DEP link setting are done atomically by the driver.
That can only happen in initiator mode, so we need to check for that
otherwise we fail to bring a p2p link in target mode.
