Function rtw_drv_init() is written in a way that assumes 'status' != _SUCCESS
as long as not explicitly set. Thus initialize 'status' to FAIL, in order to
prevent undefined behaviour if going through the exit paths. Detected by
Coverity - CID 1077832.

Fix a potential leak in the error path of rtw_set_key(). In case the requested
algorithm is not supported by the driver, the function returns without
enqueuing or freeing the already allocated command and parameter structs. Use
a centralized exit path and make sure that all memory is freed correctly.
Detected by Coverity - CID 1077716, 1077717.

Fix a potential leak in the error path of function update_bcn_wps_ie().
Move the affected input verification to the beginning of the function so
that it may return directly without leaking already allocated memory.
Detected by Coverity - CID 1077718.

Export of symbols statement must be placed right after the definition to meet
kernel coding style guidelines. This issue was reported by checkpatch.

This patch remove variables that are initialized with a constant,
are never updated, and are only used as parameter of return.
Return the constant instead of using a variable.
