PCI: Fix dyn_id add TOCTOU
Currently there is a TOCTOU issue in new_id_store() as the dyn ID insertion
in pci_add_dynid() and the pci_match_device() are in separate critical
sections.
Fix this by moving the existing ID check to inside pci_add_dynid() and only
check against the static ID table outside the critical section.
Fixes: 3853f9123c18 ("PCI: Avoid duplicate IDs in driver dynamic IDs list")
