Subject: [PATCH 4.19 291/293] qlcnic: Remove redundant unlock in qlcnic_pinit_from_rom

From: Dinghao Liu <dinghao.liu@....edu.cn>

[ Upstream commit 9ddbc2a00d7f63fa9748f4278643193dac985f2d ]

Previous commit 68233c583ab4 removes the qlcnic_rom_lock()
in qlcnic_pinit_from_rom(), but remains its corresponding
unlock function, which is odd. I'm not very sure whether the
lock is missing, or the unlock is redundant. This bug is
suggested by a static analysis tool, please advise.

Fixes: 68233c583ab4 ("qlcnic: updated reset sequence")
