ata: ahci: Clean up sysfs file on error

commit eeb25a09c5e0805d92e4ebd12c4b0ad0df1b0295 upstream.

.probe() (ahci_init_one()) calls sysfs_add_file_to_group(), however,
if probe() fails after this call, we currently never call
sysfs_remove_file_from_group().

(The sysfs_remove_file_from_group() call in .remove() (ahci_remove_one())
does not help, as .remove() is not called on .probe() error.)

Thus, if probe() fails after the sysfs_add_file_to_group() call, the next
time we insmod the module we will get:

sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:04.0/remapped_nvme'
