[PATCH] hazptr: Modify name of global variable that creates confusion

[Andreea-Cristina Bernat <bernat.ada@gmail.com>]

Since the former global variable plist was assigned to the local
variable plist from the hazptr_init() function, the following warning
was generated:
	'plist' defined but not used.
Therefore, this patch renames the global variable plist to gplist.
