[PATCH master 2/4] efi: loader: fix sign of the error passed to ERR_PTR()

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

efi_var_to_file() reports the reason it could not write the variable file
with %pe, but the one error it synthesizes itself is stored with the
wrong sign. ERR_PTR(ENOMEM) is not an error pointer, so IS_ERR() is false
and %pe prints the bogus pointer 0xc instead of "No memory".

The three other assignments to err already store negative errnos.
