Subject: [PATCH 1/1] fabric: fix search path for SRPT wwn

When converted to path link, Infiniband gid search path was replaced with a double wildcard '**'
causing no WWNs to be found and SRPT to be unusable:
No such path /srpt

This due to HCA in /sys/class/infiniband being symlinks:
$ ll /sys/class/infiniband
total 0
lrwxrwxrwx 1 root root 0 Jun 23 11:31 mlx5_0 -> ../../devices/pci0000:00/0000:00:02.6/0000:07:00.0/infiniband/mlx5_0

recurse_symlinks=True cannot be used here as HCA directories contains a 'subsystem' symlink
 pointing back to /sys/class/infiniband

Replace the double wildcard with a single one to revert to the previous behaviour and be
consistent with other fabrics.

Fixes: d3abd5df9e06 ("Convert codebase to pathlib")
