Subject: [PATCH] staging: r8822be: remove unnecessary call to memset
Git-commit: 3687994a032115e6e4f89c5715304f5361d13cfb
Patch-mainline: v4.14-rc1
References: FATE#326887

call to memset to assign 0 value immediately after allocating
memory with kzalloc is unnecesaary as kzalloc allocates the memory
filled with 0 value.

Build and tested it.
