[PATCH] qlcnic: make the array random_data static const, makes object smaller

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Don't populate the array random_data on the stack but instead it
static const. Makes the object code smaller by 66 bytes.

Before:
   text    data     bss     dec     hex filename
  52895   10976       0   63871    f97f ../qlogic/qlcnic/qlcnic_ethtool.o

After:
   text    data     bss     dec     hex filename
  52701   11104       0   63805    f93d ../qlogic//qlcnic/qlcnic_ethtool.o

(gcc version 10.2.0)
