wireless_reprobe.sh: fix Phase 2 glob — remove trailing slash that broke symlink detection

The glob pattern '$drvdir/*/' appended a trailing '/' to each
entry, which caused the shell to dereference symlinks before
the '[ -L ]' test could run.  Since the only symlinks in a USB
driver directory ARE the bound device entries (e.g. 4-1:1.0),
'[ -L path/ ]' always returned false and the unbind+rebind
never fired for any driver.

Drop the trailing '/', iterate over all entries, and filter
with '[ -L ]' on the raw name.  The module/uevent/new_id
name-skips still work correctly.
