Subject: perf intel-pt: Fix PEBS sample for XMM registers
Git-commit: 4c95ad261cfac120dd66238fcae222766754c219
References: git-fixes
X-Info: adjust for context, no 1fc632cef4ea137bc45fd0fc4cb902e374064163

The condition to add XMM registers was missing, the regs array needed to
be in the outer scope, and the size of the regs array was too small.

Fixes: 143d34a6b387b ("perf intel-pt: Add XMM registers to synthesized PEBS sample")
