fjes: fix memleaks in fjes_hw_setup

[ Upstream commit f6cc4b6a3ae53df425771000e9c9540cce9b7bb1 ]

In fjes_hw_setup, it allocates several memory and delay the deallocation
to the fjes_hw_exit in fjes_probe through the following call chain:

fjes_probe
  |-> fjes_hw_init
        |-> fjes_hw_setup
  |-> fjes_hw_exit

However, when fjes_hw_setup fails, fjes_hw_exit won't be called and thus
all the resources allocated in fjes_hw_setup will be leaked. In this
patch, we free those resources in fjes_hw_setup and prevents such leaks.
