ALSA: pcmtest: Honor the enable parameter

Browse Source 
The enable module parameter is declared and documented as "Enable
pcmtest soundcard.", but nothing reads it. Loading the module with
enable=0 still creates the card.

Return -ENODEV from mod_init() when enable is false, as the pcsp driver
does.
