pci: reduce debug log verbosity when probing

When debug level logging enabled (--log-level=8) each driver failed to
probe the device printed, like:

EAL: Driver (net_ark) doesn't match the device
EAL: Driver (net_avp) doesn't match the device
EAL: Driver (net_bnxt) doesn't match the device
EAL: Driver (net_cxgbe) doesn't match the device
EAL: Driver (net_e1000_igb) doesn't match the device
EAL: Driver (net_e1000_igb_vf) doesn't match the device
EAL: Driver (net_e1000_em) doesn't match the device
EAL: Driver (net_ena) doesn't match the device
EAL: Driver (net_enic) doesn't match the device
EAL: Driver (net_fm10k) doesn't match the device
EAL: Driver (net_i40e) doesn't match the device
EAL: Driver (net_i40e_vf) doesn't match the device
....

Overall hundreds of similar lines printed, because all drivers printed
for all devices. This is too much noise and there is already a log
message printed when device matched.

Removing the debug log completely.
