smb: use kernel_connect() and kernel_bind()

Recent changes to kernel_connect() and kernel_bind() ensure that
callers are insulated from changes to the address parameter made by BPF
SOCK_ADDR hooks. This patch wraps direct calls to ops->connect() and
ops->bind() with kernel_connect() and kernel_bind() to ensure that SMB
mounts do not see their mount address overwritten in such cases.
