tree: Ignore traddr case in nvme_lookup_ctrl()

Some FC discovery controllers return traddr strings with upper case
hexadecimal. There was is no requirement in the NVME-FC specification
that it be upper or lower case. Switch to strcasecmp for case
insentive traddr comparison.

Based on nvme-cli change 1264c6323937 ("nvme-cli: Make connect-all
matching be case insensitive")
