Sebastian Andrzej Siewior 80347cd515 x86/microcode: Remove microcode_mutex
microcode_mutex is only used by reload_store(). It has a comment saying
"to synchronize with each other". Other user of this mutex have been
removed in the commits

  181b6f40e9 ("x86/microcode: Rip out the OLD_INTERFACE").
  b6f86689d5 ("x86/microcode: Rip out the subsys interface gunk")

The sysfs interface does not need additional synchronisation vs itself
because it is provided as kernfs_ops::mutex which is acquired in
kernfs_fop_write_iter().

Remove the superfluous microcode_mutex.
