When using qemu pcie_aer_inject_error command to inject
an error on e1000e, the error is not sent to the guest.
The problem is caused by the e1000e did not initialize
the device error control registers mask. Since the
default mask is 0, any value written to the registers
will be masked off.

Followed pci-bridge/xio3130_downstream.c to use
pcie_cap_deverr_init() to initialize the mask.
