ASoC: sma1307: Fix error handling in sma1307_setting_loaded()

[ Upstream commit 012a6efcc805308b1d90a1056ba963eb08858645 ]

There are a couple bugs in this code:

1) The cleanup code calls kfree(sma1307->set.header) and
   kfree(sma1307->set.def) but those functions were allocated using
   devm_kzalloc().  It results in a double free.  Delete all these
   kfree() calls.

2) A missing call to kfree(data) if the checksum was wrong on this error
   path:
	if ((sma1307->set.checksum >> 8) != SMA1307_SETTING_CHECKSUM) {
   Since the "data" pointer is supposed to be freed on every return, I
   changed that to use the __free(kfree) cleanup attribute.
