If one of these memory allocations fail, a NULL pointer dereference will
occur later on.
Return -ENOMEM instead.
There is no need to free the resources already allocated, this is done
by the caller (i.e. 'rtl8192_usb_probe()') which calls
'rtl8192_usb_deleteendpoints()'.
The calling graph is:
rtl8192_usb_probe
--> rtl8192_init
--> rtl8192_usb_initendpoints

The error handling path in 'rtl8192_usb_probe' must also be fixed because
it is bogus. Will do that in another patch.
