staging: rtl8192e: remove set but not used variable 'data_len' 



Fixes gcc '-Wunused-but-set-variable' warning:

 In function ieee80211_ccmp_encrypt:
drivers/staging/rtl8192u/ieee80211/ieee80211_crypt_ccmp.c:162:6:
 warning: variable data_len set but not used [-Wunused-but-set-variable]

It is not used since commit 5ee52656 ("staging:
rtl8192e: rtllib_crypt_ccmp.c: Use crypto API ccm(aes)")
