KEYS: fix "ca_keys=" partial key matching
The call to asymmetric_key_hex_to_key_id() from ca_keys_setup()
silently fails with -ENOMEM. Instead of dynamically allocating
memory from a __setup function, this patch defines a variable
and calls __asymmetric_key_hex_to_key_id(), a new helper function,
directly.
This bug was introduced by 'commit 46963b774d44 ("KEYS: Overhaul
key identification when searching for asymmetric keys")'.
Changelog:
- for clarification, rename hexlen to asciihexlen in
asymmetric_key_hex_to_key_id()
- add size argument to __asymmetric_key_hex_to_key_id() - David Howells
- inline __asymmetric_key_hex_to_key_id() - David Howells
- remove duplicate strlen() calls
