Bluetooth: cmtp: Remove unnecessary null test

This patch removes the null test on ctrl. ctrl is initialized at the
beginning of the function to &session->ctrl. Since session is
dereferenced prior to the null test, session must be a valid pointer,
and &session->ctrl cannot be null.

The following Coccinelle script is used for detecting the change:

@r@
expression e,f;
identifier g,y;
statement S1,S2;
@@

*e = &f->g
<+...
 f->y
 ...+>
*if (e != NULL || ...)
 S1 else S2
