Fix maybe uninitialized

Browse Source 
As of gcc 5.1.1 20150618 (Red Hat 5.1.1-4) the -Werror=maybe-uninitialized
check detects that 'snapname' in recv_incremental_replication() may not be
initialized.  Explicitly initialize the variable to resolved the warning.

  libzfs_sendrecv.c: In function ‘recv_incremental_replication’:
  libzfs_sendrecv.c:2019:2: error: ‘snapname’ may be used uninitialized in
    (void) snprintf(buf, sizeof (buf), "%s@%s", fsname, snapname);
