Subject: [PATCH] powerpc/tm: Update function prototype comment

References: bsc#1118338
Patch-mainline: v4.19-rc1
Git-commit: a596a7e91710d26fd862e3b7031c4012974583f2

In commit eb5c3f1c8647 ("powerpc: Always save/restore checkpointed regs
during treclaim/trecheckpoint") __tm_recheckpoint was modified to no
longer take the second parameter 'unsigned long orig_msr' as part of a
TM rewrite to simplify the reclaiming/recheckpointing process.

There is a comment in the asm file where the function is delcared which
has an incorrect prototype with the 'orig_msr' parameter.

This patch corrects the comment.
