[PATCH next] ASoC: rt1320: Fix retry checking in rt1320_rae_load()

[Dan Carpenter]

This loop iterates 200 times and then gives up.  The problem is that
currently the loop exits with "retry" set to -1 on the failure path but
the check for failure expects it to be 0.  Change from a post-op to a
pre-op so that it exits with "retry" set to 0.

Technically now the loop only tries 199 times after my change, however
I am okay with that.
