Merge branch 'vsock-fix-so_zerocopy-on-accept-ed-vsocks'

Michal Luczaj says:

====================
vsock: Fix SO_ZEROCOPY on accept()ed vsocks

vsock has its own handling of setsockopt(SO_ZEROCOPY). Which works just
fine unless socket comes from a call to accept(). Because
SOCK_CUSTOM_SOCKOPT flag is missing, attempting to set the option always
results in errno EOPNOTSUPP.
