staging: qlge: Retire the driver
No significant improvements have been done to this driver since commit
a7c3ddf29a78 ("staging: qlge: clean up debugging code in the QL_ALL_DUMP
ifdef land") in January 2021. The driver should not stay in staging
forever. Since it has been abandoned by the vendor and no one has stepped
up to maintain it, delete it.
If some users manifest themselves, the driver will be restored to
drivers/net/ as suggested in the linked message.
