  a2dp: Fix loading of remote SEP from cache

Commit 912f5efb0dd9 ("a2dp: Fix handling of codec capability storage")
added an 'i >= 2' condition to the loop that parses the stored codec
capabilities. Since i starts at 0 the loop body never runs, i stays 0,
and the subsequent 'if (i != size)' check discards every endpoint found
in the cache:

  load_remote_sep() Unable to load LastUsed: rseid 6 not found

With no remote SEP loaded, avdtp_discover() can no longer take the
cached path and issues AVDTP Discover/Get All Capabilities on every
reconnect, and a2dp_setup_remote_path() returns NULL so the transport
ends up at /org/bluez/hciX/dev_YY/fd0 instead of .../sepN/fd0.

The condition was presumably meant to bound the writes into data[128],
which the original commit did not actually fix: caps is read with
'%512s' so size / 2 can be up to 256. Validate size up front instead.
