niu: fix warnings in drivers/net/niu.c
these warnings:
drivers/net/niu.c: In function ‘serdes_init_niu_1g_serdes’:
drivers/net/niu.c:451: warning: ‘sig’ may be used uninitialized in this function
drivers/net/niu.c: In function ‘serdes_init_niu_10g_serdes’:
drivers/net/niu.c:550: warning: ‘sig’ may be used uninitialized in this function
triggers because GCC does not recognize that the max_retry loop
always initializes 'sig', due to max_retry != 0.
Annotate them.
