staging: rtl8712: Fix possible buffer overrun
commit 300cd664865bed5d50ae0a42fb4e3a6f415e8a10 upstream.
In commit 8b7a13c3f404 ("staging: r8712u: Fix possible buffer
overrun") we fix a potential off by one by making the limit smaller.
The better fix is to make the buffer larger. This makes it match up
with the similar code in other drivers.
