Message

When loading certificates list from EFI variables, the error
messages and efi status codes always be emitted to dmesg. It looks
ugly:

[    2.335031] Couldn't get size: 0x800000000000000e
[    2.335032] Couldn't get UEFI MokListRT 
[    2.339985] Couldn't get size: 0x800000000000000e
[    2.339987] Couldn't get UEFI dbx list

This cosmetic patch set moved the above messages to the error
handling code path. And, it adds a function to convert EFI status
code to a string for improving the readability of debug log. The function
can also be used in other EFI logs.

v2:
The convert function be moved to efi.c

Lee, Chun-Yi (2):
  efi: add a function to convert the status code to a string
  efi: show error messages only when loading certificates is failed
