hw/pci: Add parenthesis to PCI_BUILD_BDF macro
The bus parameter in the macro PCI_BUILD_BDF is not surrounded by
parenthesis. This can create a compile error when warnings are
treated as errors or can potentially create runtime errors due to the
operator precedence.
For instance:
file.c:x:32: error: suggest parentheses around '-' inside '<<'
[-Werror=parentheses]
171 | uint16_t bdf = PCI_BUILD_BDF(a - b, sdev->devfn);
| ~~^~~
include/hw/pci/pci.h:19:41: note: in definition of macro
'PCI_BUILD_BDF'
19 | #define PCI_BUILD_BDF(bus, devfn) ((bus << 8) | (devfn))
| ^~~
cc1: all warnings being treated as errors
