Subject: [PATCH v4] staging: qlge: fix build breakage with dumping enabled

This fixes commit 0107635e15ac
("staging: qlge: replace pr_err with netdev_err") which introduced an
build breakage of missing `struct ql_adapter *qdev` for some functions
and a warning of type mismatch with dumping enabled, i.e.,

$ make CFLAGS_MODULE="-DQL_ALL_DUMP -DQL_OB_DUMP -DQL_CB_DUMP \
    -DQL_IB_DUMP -DQL_REG_DUMP -DQL_DEV_DUMP" M=drivers/staging/qlge

qlge_dbg.c: In function ‘ql_dump_ob_mac_rsp’:
qlge_dbg.c:2051:13: error: ‘qdev’ undeclared (first use in this function); did you mean ‘cdev’?
 2051 |  netdev_err(qdev->ndev, "%s\n", __func__);
      |             ^~~~
qlge_dbg.c: In function ‘ql_dump_routing_entries’:
qlge_dbg.c:1435:10: warning: format ‘%s’ expects argument of type ‘char *’, but argument 3 has type ‘int’ [-Wformat=]
 1435 |        "%s: Routing Mask %d = 0x%.08x\n",
      |         ~^
      |          |
      |          char *
      |         %d
 1436 |        i, value);
      |        ~
      |        |
      |        int
qlge_dbg.c:1435:37: warning: format ‘%x’ expects a matching ‘unsigned int’ argument [-Wformat=]
 1435 |        "%s: Routing Mask %d = 0x%.08x\n",
      |                                 ~~~~^
      |                                     |
      |                                     unsigned int

Note that now ql_dump_rx_ring/ql_dump_tx_ring won't check if the passed
parameter is a null pointer.
