net/hinic: Remove the initialization of the global variable g_uld_info

driver inclusion
category: bugfix
bugzilla: 47993

-----------------------------------------------------------------------

In the hinic driver, the g_uld_info global variable is assigned to all
0s, and the'designated init' alarm is reported at compile time. The
global variable defaults to all 0s, and the assignment of 0s is not
necessary.
