net: gianfar_ptp: move set_fipers() to spinlock protecting area
[ Upstream commit 11d827a993a969c3c6ec56758ff63a44ba19b466 ]
set_fipers() calling should be protected by spinlock in
case that any interrupt breaks related registers setting
and the function we expect. This patch is to move set_fipers()
to spinlock protecting area in ptp_gianfar_adjtime().
