Arnd Bergmann 14e3cdbb00 media: don't drop front-end reference count for ->detach 
A bugfix introduce a link failure in configurations without CONFIG_MODULES:

In file included from drivers/media/usb/dvb-usb/pctv452e.c:20:0:
drivers/media/usb/dvb-usb/pctv452e.c: In function 'pctv452e_frontend_attach':
drivers/media/dvb-frontends/stb0899_drv.h:151:36: error: weak declaration of 'stb0899_attach' being applied to a already existing, static definition

The problem is that the !IS_REACHABLE() declaration of stb0899_attach()
is a 'static inline' definition that clashes with the weak definition.

I further observed that the bugfix was only done for one of the five users
of stb0899_attach(), the other four still have the problem.  This reverts
the bugfix and instead addresses the problem by not dropping the reference
count when calling '->detach()', instead we call this function directly
in dvb_frontend_put() before dropping the kref on the front-end.

I first submitted this in early 2018, and after some discussion it
was apparently discarded.  While there is a long-term plan in place,
that plan is obviously not nearing completion yet, and the current
kernel is still broken unless this patch is applied.
