perf arm-spe: Remove redundant checking for "full_auxtrace"

mainline inclusion
from mainline-v5.14-rc1
commit afe360a8
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4NGPV


CVE: NA

-------------------------------------------------

The option "opts->full_auxtrace" is checked at the earlier place, if it
is false the function will directly bail out.  So remove the redundant
checking for "opts->full_auxtrace".
