wifi: ath11k: Silence remoteproc probe deferral prints

Upon failing to resolve the remoteproc phandle one ath11k_dbg() and one
ath11k_err() is used to tell the user about the (presumably) temporary
failure.

Reduce the log spam by removing the duplicate print and switching to
dev_err_probe(), in line with how ath12k handles this error.
