Sudip Mukherjee c89e5b8024 PCI/AER: include header file
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. Include errno.h so that we have the definitions of the error
codes.

Fixes: a0a3408ee6 ("NVMe: Add pci error handlers")
