[PATCH v1 11/11] perf/x86/amd: Remove exclude_guest check from perf_ibs_init()

[Manali Shukla <manali.shukla@amd.com>]

Currently IBS driver doesn't allow the creation of IBS event with
exclue_guest set. As a result, amd_ibs_init() returns -EINVAL if
IBS event is created with exclude_guest set.

With the introduction of mediated PMU support, software-based handling
of exclude_guest is permitted for PMUs that have the
PERF_PMU_CAP_MEDIATED_VPMU capability.

Since ibs_op and ibs_fetch pmus has PERF_PMU_CAP_MEDIATED_VPMU
capability set, update perf_ibs_init() to remove exclude_guest check.
