Peilin Ye d429362b3d net/smc: Prevent kernel-infoleak in __smc_diag_dump()
[ Upstream commit ce51f63e63 ]

__smc_diag_dump() is potentially copying uninitialized kernel stack memory
into socket buffers, since the compiler may leave a 4-byte hole near the
beginning of `struct smcd_diag_dmbinfo`. Fix it by initializing `dinfo`
with memset().

Fixes: 4b1b7d3b30 ("net/smc: add SMC-D diag support")
