[PATCH] arch/sparc: remove unused varible paddrbase in function leon_swprobe()

[alexs]

From: Alex Shi <alexs@xxxxxxxxxx>

commit f22ed71cd602 ("sparc32,leon: SRMMU MMU Table probe fix") change
return value from paddrbase to 'pte', but left the varible here.
That causes a build warning for this varible, so we may remove it.
