Find a file
Hans de Goede b3a02322d4 ucm: Only look in ucm[1] or ucm2 dir once we've found a config file in one 
Unless environment variables are set, then configuration_filename()
when initially called by load_master_config() will first try to find
the requested master-config under <prefix>/alsa/ucm2 and then under
<prefix>/alsa/ucm.

Once a master-config is found this way, we should set conf_format to
match, so that subsequent lookups only look under the same directory
as where the master-config was found.

This fixes 2 problems:
1. uc_mgr_config_load() looking under <prefix>/alsa/ucm for includes for
   UCM2 profiles because it is called with uc_mgr->conf_format as format
   and before this commit that would stay 0 when autodetecion is used.

2. parse_verb_file() possibly loading an UCM2 verb-file for an UCM1 profile,
   the chance of this happening is small as this means that even though
   there is no UCM2 master-config there is an UCM2 profile dir matching
   uc_mgr->conf_file_name, which would be weird.

Fixes: aba2260ae7 ("ucm: switch to ucm2 directory and v2 format, keep backward compatibility")
