The current error-checking of me->stages in sh_css_sp_init_pipeline()
has some issues / weirdness:
1. It is checked at the top of the function, but only using the atomisp
custom assert() macro which e.g. smatch does not recognize
2. It is first dereferenced in "first_binary = me->stages->binary", but
outside of the assert it is checked much later, triggering the following
smatch warning:
drivers/staging/media/atomisp/pci/sh_css_sp.c:1255 sh_css_sp_init_pipeline()
warn: variable dereferenced before check 'me->stages' (see line 1224)
Drop the custom assert() calls (note 'me' is never NULL) and instead add
a regular check for me->stages not being set.
