The venus driver fails to check if dev_pm_opp_find_freq_{ceil,floor}()
returns an error pointer before calling dev_pm_opp_put(). This causes
a crash when OPP tables are not present in device tree.
Unable to handle kernel access to user memory outside uaccess routines

pc : dev_pm_opp_put+0x1c/0x4c
lr : core_clks_enable+0x4c/0x16c [venus_core]
Add IS_ERR() checks before calling dev_pm_opp_put() to avoid
dereferencing error pointers.
