Sergey SENOZHATSKY 17649c90ff regmap: fix a NULL pointer dereference in __regmap_init 
__regmap_init() may receive a NULL `struct regmap_bus *bus' pointer,
for example, from snd_hdac_regmap_init(), and it make sure that it
does not NULL deference `bus`, except around ->max_raw_read and
->max_raw_write initialisation. Add missing check.
