cpufreq/amd-pstate: Fix per-policy boost flag incorrect when fail

Browse source 
Commit c8c68c38b5 ("cpufreq: amd-pstate: initialize core precision
boost state") sets per-policy boost flag to false when boost fail.
However, this boost flag will be set to reverse value in
store_local_boost() and cpufreq_boost_trigger_state() in cpufreq.c. This
will cause the per-policy boost flag set to true when fail to set boost.
Remove the extra assignment in amd_pstate_set_boost() and keep all
operations on per-policy boost flag outside of set_boost() to fix this
problem.
