dax: Return errors from dax_core_init()

Browse Source 
dax_core_init() returns success when either the character device
number allocation or DAX bus registration fails, even though the
error paths have already released the initialized resources.

For modular DAX, this allows the module to remain loaded despite
failed initialization, leaving subsequent users and module removal
to access resources that have already been released.

Return the error code from the failed operation so that module
loading fails rather than reporting successful initialization
after the resources have been released.
