Larry Finger 9c8fc4b323 staging: r8188eu: Fix warning of array overflow in ioctl_linux.c
[ Upstream commit 96f0a54e8e ]

Building with -Warray-bounds results in the following warning plus others
related to the same problem:

Although it is unlikely that anyone is still using WEP encryption, the
size of the allocation needs to be increased just in case.
