PCI/IOV: Enlarge virtfn sysfs name buffer
[ Upstream commit ea0b5aa5f184cf8293c93163f0fb00505190d431 ]
The sysfs link name "virtfn%u" constructed by pci_iov_sysfs_link() requires
17 bytes to contain the longest possible string. Increase VIRTFN_ID_LEN to
accommodate that.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
