ASoC: cs35l56: fix reversed if statement in cs35l56_dspwait_asp1tx_put()

It looks like the "!" character was added accidentally.  The
regmap_update_bits_check() function is normally going to succeed.  This
means the rest of the function is unreachable and we don't handle the
situation where "changed" is true correctly.

Fixes: 07f7d6e7
