powerpc/eeh: Fix crashes in eeh_report_resume()
The notify_resume() callback in eeh_ops is NULL on powernv, leading to
crashes:
NIP (null)
LR eeh_report_resume+0x218/0x220
Call Trace:
eeh_report_resume+0x1f0/0x220 (unreliable)
eeh_pe_dev_traverse+0x98/0x170
eeh_handle_normal_event+0x3f4/0x650
eeh_handle_event+0x54/0x380
eeh_event_handler+0x14c/0x210
kthread+0x168/0x1b0
ret_from_kernel_thread+0x5c/0xb4
Fix it by adding a check before calling it.
