In the last error path in rtl_pci_probe(), the cleanup functions are
skipped due to a wrong goto label. Moreover, the successful call to
rtl_init_rfkill(), ieee80211_register_hw(), rtl_debug_add_one() have to
be reverted. Fix this issue by updating the labels and adding the
relevant cleanup functions to the last error path.

Compile tested only. Issue found using static analysis.

v1->v2:
- Added a call to rtl_debug_remove_one() in the error path, as suggested
  by Ping-Ke Shih, to free the debugfs resources which were successfully
  allocated in that path.
- Updated commit message to mention rtl_debug_add_one()
