V4L/DVB: drivers/media/dvb/frontends: remove duplicate structure field initialization

The read_status field is initialized twice to the same value.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r@
identifier I, s, fld;
position p0,p;
expression E;
@@

struct I s =@p0 { ... .fld@p = E, ...};

@s@
identifier I, s, r.fld;
position r.p0,p;
expression E;
@@

struct I s =@p0 { ... .fld@p = E, ...};

@script:python@
p0 << r.p0;
fld << r.fld;
ps << s.p;
pr << r.p;
@@

if int(ps[0].line)<int(pr[0].line) or int(ps[0].column)<int(pr[0].column):
  cocci.print_main(fld,p0)
// </smpl>
