This patch is to fix a compiler warning of maybe-uininitialized-variable that is generated from gcc when the -O3 flag is used. In the function e1000_reset_hw_80003es2lan(), the variable krmn_reg_data is first given a value by being passed to a register read function as a pass-by-reference parameter. But, the return value of that read function was never checked to see if the read failed and the variable not given an initial value. The compiler was smart enough to spot this. This patch is to check the return value for that read function and return it, if an error occurs, without trying to utilize the value in kmrn_reg_data.
