net: qlcnic: add missed unlock in qlcnic_83xx_flash_read32
[ Upstream commit 0a298d133893c72c96e2156ed7cb0f0c4a306a3e ]
qlcnic_83xx_unlock_flash() is called on all paths after we call
qlcnic_83xx_lock_flash(), except for one error path on failure
of QLCRD32(), which may cause a deadlock. This bug is suggested
by a static analysis tool, please advise.
Fixes: 81d0aeb0a4fff ("qlcnic: flash template based firmware reset recovery")
