[PATCH] arm64: Remove the check for CONFIG_TINY_RCU

[Ryo Takakura]

Since the commit 4b3dc9679cf77 ("arm64: force CONFIG_SMP=y and remove
redundant #ifdefs"), arm64 defaults to CONFIG_SMP but TINY_RCU is cofigured
only for !SMP systems.

Remove the check for CONFIG_TINY_RCU as it should always be false.
