regulator: core: Ensure debugfs is fully initialized

Browse Source 
regulator->debugfs is NULL when sysfs_create_link_nowarn() return -EEXIST,
and triggering the following warning:

[    2.426974] debugfs: File 'uA_load' in directory '/' already present!
[    2.426983] debugfs: File 'min_uV' in directory '/' already present!
[    2.426991] debugfs: File 'max_uV' in directory '/' already present!
[    2.426999] debugfs: File 'constraint_flags' in directory '/' already present!
