Currently if the ctx->spkamp is not recognized an error message is
reported but the code continues to set up the device with uninitialized
variables such as the number of widgets.  Fix this by returning -EINVAL
for unrecognized speaker amplifier types.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: e1435a1feb18 ("ASoC: Intel: bxt-da7219-max98357a: support MAX98390 speaker amp")

Sounds good, thanks Colin.
