rG0f7bdeadaf9d: ixl: Initialize the extended RSS key

Summary

Zero the complete 52-byte RSS key buffer before fetching the common
40-byte key.  Both the X722 AdminQ path and the register path consume all
52 bytes; the trailing extended-key bytes must not come from uninitialized
stack storage.  This matches the zero padding already used by iavf and ice.

Remove the unused driver-default key helper and its declaration.  Keep
the standard key, hash selections, and indirection policy unchanged.
