misc: xilinx_sdfec: Fix a couple small information leaks
These structs have holes in them so we end up disclosing a few bytes of
uninitialized stack data.
drivers/misc/xilinx_sdfec.c:305 xsdfec_get_status() warn: check that 'status' doesn't leak information (struct has a hole after 'activity')
drivers/misc/xilinx_sdfec.c:449 xsdfec_get_turbo() warn: check that 'turbo_params' doesn't leak information (struct has a hole after 'scale')
We need to zero out the holes with memset().
Fixes: 6bd6a690c2e7 ("misc: xilinx_sdfec: Add stats & status ioctls")
