staging: rtl8188eu: core: Remove redundant memset before memcpy
The region set by the call to memset, immediately overwritten by the
subsequent call to memcpy makes the memset redundant.
This patch removes the redundant memset before memcpy using the
following coccinelle script:
@@
expression e1,e2,e3,e4;
@@
- memset(e1,e2,e3);
memcpy(e1,e4,e3);
