This patch replaces NULL values returned by vc_vchi_audio_init(...) with
error pointer values:
	- Return ERR_PTR(-EINVAL) when too many instances of audio
	  service are initialised
	- Return ERR_PTR(-ENOMEM) when kzalloc fails
	- RETURN ERR_PTR(-EPERM) when vchi connections fail to open

Similarly, a NULL check where vc_vchi_audio_init(...) is called is
replaced by IS_ERR(..)

In various functions a return code variable is defined at the top of
function, for example;

rc = -ENODEV;

and then the variable is returned. This makes it harder to read since
it separates the error code from the return site.

Return the error code directly instead of using a variable.

Convert macro GAT_CONFIG to static inline function as static inline

'auth_type - 1' is used as an index into a key table. Adding a variable
appropriately named simplifies the code and adds meaning when
reading. Adding a pointer variable of type struct *kpa_key_t adds to
readability by removing the table access each time the key is used.

The key index is used to create a string so having it named adds
additional meaning when creating the string.

Declare variable 'key_index' and define it at declaration time. Declare
a pointer variable 'key' and define it to point to the correct key in
the key table.

Checkpatch emits WARNING: Too many leading tabs - consider code
refactoring. Function contains 5 levels of nesting and 14 local
variables. Code can be simplified and nesting reduced by refactoring
into separate functions.

WPA code is contained and may be factored out into a separate
function. This will reduce the length and complexity of
hostif_data_indication(). At times within the WPA code errors result
in the function returning. In order to maintain this behaviour new
function should return a status integer.

Factor out WPA code into separate function. Add only code needed to
get compilation to pass, including modifying return statements. Make
no other code changes, program logic is unchanged.
