Subject: firmware: arm_sdei: fix wrong of_node_put() in init function
Git-commit: c3790b3799f8d75d93d26f6fd7bb569fc8c8b0cb
Patch-mainline: v5.0-rc1
References: bsc#1116839

After finding a "firmware" dt node arm_sdei tries to match it's
compatible string with it. To do so it's calling of_find_matching_node()
which already takes care of decreasing the refcount on the "firmware"
node. We are then incorrectly decreasing the refcount on that node
again.

This patch removes the unwarranted call to of_node_put().
