powerpc/book3s64/radix: Rename CPU_FTR_P9_TLBIE_BUG feature flag
commit 09ce98cacd51fcd0fa0af2f79d1e1d3192f4cbb0 upstream.
Rename the #define to indicate this is related to store vs tlbie
ordering issue. In the next patch, we will be adding another feature
flag that is used to handles ERAT flush vs tlbie ordering issue.
Cc: stable@vger.kernel.org # v4.14
Fixes: a5d4b5891c2f ("powerpc/mm: Fixup tlbie vs store ordering issue on POWER9")
