ALSA: hda: Fix missing pointer check in hda_component_manager_init function

The __component_match_add function may assign the 'matchptr' pointer
the value ERR_PTR(-ENOMEM), which will subsequently be dereferenced.

The call stack leading to the error looks like this:

hda_component_manager_init
|-> component_match_add
    |-> component_match_add_release
        |-> __component_match_add ( ... ,**matchptr, ... )
            |-> *matchptr = ERR_PTR(-ENOMEM);       // assign
|-> component_master_add_with_match( ...  match)
    |-> component_match_realloc(match, match->num); // dereference

Add IS_ERR() check to prevent the crash.
