[PATCH] powerpc/perf: Use SIER_USER_MASK while updating SPRN_SIER for EBB events

[Athira Rajeev]

commit 330a1eb7775b ("powerpc/perf: Core EBB support for 64-bit book3s")
defines user mask for SIER. But this is not used in ebb_switch_out while
saving SPR's. Patch fixes this by updating SPRN_SIER with the user mask.
