[Qemu-devel] [PATCH] error: fixed error_set_errno() to deal with a negative type of os_error.

[SeokYeon Hwang]

Negative type of errno like -ERRNO is used a lot by developers. Therefore, 
error_set_errno() is modified to deal with a negative type of os_error.
(Negative type is used at pcie_cap_slot_hotplug_common() in hw/pci/pcie.c)
