[PATCH v3] staging: rtl8723bs: Improve error handling

[Bera Yüzlü]

Remove unnecessary ret variable and goto exit pattern. The function now
returns immediately when an error occurs. Additionally, ensure that
intf_free_irq() is called when pm_netdev_open() fails to avoid leaving
the allocated IRQ uncleared.

V3: Fixed patch description.
V2: Used int_free_irq() in error condition.
