[PATCH] nvme: arrange header files

[Sudip Mukherjee]

We are having build failure with sparc allmodconfig with the error:
drivers/nvme/host/pci.c:15:0:
include/linux/aer.h: In function 'pci_enable_pcie_error_reporting':
include/linux/aer.h:49:10: error: 'EINVAL' undeclared (first use in this function)

The file aer.h is using the error values but they are defined in
errno.h. So if we keep aer.h at the top of header file then we do not
have any definition of EINVAL.

Fixes: a0a3408ee614 ("NVMe: Add pci error handlers")

If you insist on having the headers in alphabetical order then I can
send v2 by including errno.h in aer.h
