[PATCH] Staging: rtl8192e: remove redundant null check on array alg

[Colin King <colin.king@xxxxxxxxxxxxx>]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

u.crypt.alg is an array of u8 integers and hence the null check on
this array is redundant and can be removed.

Detected with CoverityScan, CID#146583 ("Array compared against 0")
