i3c: mipi-i3c-hci-pci: Set drvdata before creating LTR sysfs attribute
intel_i3c_init() creates the pm_qos_latency_tolerance_us sysfs attribute
before probe calls pci_set_drvdata(). A userspace write to the attribute
can therefore invoke intel_ltr_set(), which uses pci_get_drvdata(),
before drvdata has been initialized.
Move pci_set_drvdata() before hci->info->init() so drvdata is available
before the sysfs attribute becomes accessible.
