nfc_llc_register() calls pass a string literal as the 'name' parameter.

So kstrdup_const() can be used instead of kfree() to avoid a memory
allocation in such cases.

v2: Add a new helper function, nfc_llc_del_engine(), to reduce code
    duplication. This is needed to address Jakub Kicinski's comment
    about nfc_llc_exit() that was not updated in v1.

v1: https://lore.kernel.org/all/6d2b8c390907dcac2e4dc6e71f1b2db2ef8abef1.1705744530.git.christophe.jaillet@wanadoo.fr/

Christophe JAILLET (2):
  nfc: hci: Introduce nfc_llc_del_engine() to reduce code duplication
  nfc: hci: Save a few bytes of memory when registering a 'nfc_llc'
    engine
