[PATCH] ASoC: cs-amp-lib: Simplify overcomplicated error return

[Richard Fitzgerald <rf@opensource.cirrus.com>]

In cs_amp_devm_get_dell_ssidex() remove an unnecessary special case check
on -ENOENT that just returned -ENOENT. The other branch of the if()
statement returned the error, which would of course return -ENOENT if the
error was -ENOENT and so do exactly the same as the first branch.

The whole if statement is identical to just returning the original pointer
if it is an error value.
