Subject: Don't segfault if the first 'auto-key-locate' option is 'clear'.

* g10/getkey.c (free_akl): If AKL is NULL, just return.

Backported from f2ee673c99825d5189631031ddec2dbf54dbd482.  Note:
unlike in 2.1, in 2.0 this bug is not (currently) triggered since
parse_auto_key_locate doesn't recognize "clear".

Signed-off-by: Neal H. Walfield <neal@g10code.com>.
Reported-by: Sami Farin.
GnuPG-bug-id: 2045
