[PULL 26/53] pcie: pcie_cap_slot_write_config(): use correct macro |

From: Vladimir Sementsov-Ogievskiy <vsementsov@yandex-team.ru>
PCI_EXP_SLTCTL_PIC_OFF is a value, and PCI_EXP_SLTCTL_PIC is a mask.
Happily PCI_EXP_SLTCTL_PIC_OFF is a maximum value for this mask and is
equal to the mask itself. Still the code looks like a bug. Let's make
it more reader-friendly.
