platform: mellanox: Fix a resource leak in an error handling path in probing flow

Fix missed resource deallocation in rollback flows.

Currently if an error occurs after a successful
mlxplat_i2c_main_init(), mlxplat_i2c_main_exit() call is missed in
rollback flow.
Thus, some resources are not de-allocated.

Move mlxplat_pre_exit() call from mlxplat_remove() into
mlxplat_i2c_main_exit().

Call mlxplat_i2c_main_exit() instead of calling mlxplat_pre_exit() in
mlxplat_probe() error handling flow.

Unregister 'priv->pdev_i2c' device in mlxplat_i2c_main_init() cleanup
flow if this device was successfully registered.
