rtl8192c:dm: Properly initialize local array and set value.

commit 7c8f0db0d024efda38976fc2acf7743f458e1d96 upstream.

GCC 4.8 is spitting out uninitialized-variable warnings against
"drivers/net/wireless/rtlwifi/rtl8192c/dm_common.c".  This patch adds
initialization to the variable and properly sets its value.
