Jia-Ju Bai de3d01fd85 xen: xen-pciback: Replace GFP_ATOMIC with GFP_KERNEL in pcistub_reg_add

pcistub_reg_add() is never called in atomic context.

pcistub_reg_add() is only called by pcistub_quirk_add, which is
only set in DRIVER_ATTR().

Despite never getting called from atomic context,
pcistub_reg_add() calls kzalloc() with GFP_ATOMIC,
which does not sleep for allocation.
GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL,
which can sleep and improve the possibility of sucessful allocation.

This is found by a static analysis tool named DCNS written by myself.
And I also manually check it.
