fb: sh-mobile: Fix deadlock risk between lock_fb_info() and console_lock() commit 4a47a0e09c504e3ce0ccdb405411aefc5b09deb8 upstream. Following on Herton's patch "fb: avoid possible deadlock caused by fb_set_suspend" which moves lock_fb_info() out of fb_set_suspend() to its callers, correct sh-mobile's locking around call to fb_set_suspend() and the same sort of deaklocks with console_lock() due to order of taking the lock. console_lock() must be taken while fb_info is already locked and fb_info must be locked while calling fb_set_suspend().
