net: caif: add proper error handling
commit a2805dca5107d5603f4bbc027e81e20d93476e96 upstream.
caif_enroll_dev() can fail in some cases. Ingnoring
these cases can lead to memory leak due to not assigning
link_support pointer to anywhere.
Fixes: 7c18d2205ea7 ("caif: Restructure how link caif link layer enroll")
