Subject: [PATCH 1/4] nvme: do not leak an open file handle
We performed a "sec_fd=open(cfg.file)" earlier, so we should not
overwrite the handle.

Subject: [PATCH 3/4] nvme-cli: nvmf-connect@.service: Remove matching from
default syntax
commit 53aab69a0add added the "--matching" argument to the systemd
connect script that issues connect-all to a discovery controller. When
this argument is used, only discovery log entries whose target port
traddr's match the traddr of the discovery controller will be connected
to. This eliminates the ability to do referrals by the discovery
controller.
Revert the commit so that the "--matching" argument is not default
behavior.

Subject: [PATCH 4/4] nvme-cli: Make connect-all matching be case insensitive
The comparison routine that checks discovery controller traddr with a
discovery log traddr uses a simple strncmp. For FC, which kicks off
connect-all requests vay systemd, the nvme-fc transport will build
traddr strings with lower case hexadecimal. Some FC discovery
controllers return traddr strings with upper case hexadecimal. There
was is no rqmt in the NVME-FC spec that it be upper or lower case.
Given the case difference, the connect-all fails the match logic and
doesn't connect to storage.
Revise the traddr comparison routine to duplicate the strings and
convert them to lower case for comparison.
