staging: usbip: use kcalloc instead of kzalloc for array allocations

The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.

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.

staging: rtl8188eu: fix potential leak in rtw_set_key()

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.
