Bluetooth: btwilink: remove unnecessary static in bt_ti_probe()

Remove unnecessary static on local variable hst.
Such variable is initialized before being used,
on every execution path throughout the function.
The static has no benefit and, removing it reduces
the object file size.

This issue was detected using Coccinelle and the
following semantic patch:

@bad exists@
position p;
identifier x;
type T;
@@

static T x@p;
...
x = <+...x...+>

@@
identifier x;
expression e;
type T;
position p != bad.p;
@@

-static
 T x@p;
 ... when != x
     when strict
?x = e;

In the following log you can see the difference in the object file size.
This log is the output of the size command, before and after the code
change:

before:
   text    data     bss     dec     hex filename
   4029    2528     128    6685    1a1d drivers/bluetooth/btwilink.o

after:
   text    data     bss     dec     hex filename
   4007    2472      64    6543    198f drivers/bluetooth/btwilink.o
