Subject: [PATCH] x86/efi: Delete misleading efi_printk() error message

From: Matt Fleming <matt.fleming@...el.com>

A number of people are reporting seeing the "setup_efi_pci() failed!"
error message in what used to be a quiet boot,

  https://bugzilla.kernel.org/show_bug.cgi?id=81891

The message isn't all that helpful because setup_efi_pci() can return a
non-success error code for a variety of reasons, not all of them fatal.

Drop the efi_printk() now that we have more fine-grained, and more
specific, error messages throughout the *setup_efi_pci*() code paths.

This patch is based on top of Andre's ("x86/efi: Adding efi_printks on
memory allocationa and pci.reads") sitting on the 'next' branch.
