There is no failure checking on the param value which will be allocated
memory by kmalloc. Add a null pointer checking statement. Then goto error:
and return -ENOMEM error code when kmalloc is failed.

Changes since v1:
- Return with -ENOMEM directly, instead of goto error: then return.
- [Patch v3 1/2] is same with [patch v2]

It needs to free of allocated params value in the goto error statement.
Signed-off-by: Ji-Hun Kim <ji_hun.kim@samsung.com>

Changes since v2:
- add kfree(params) on the error case of the function
- rename unclear goto statement name
- declare the params value at start of the function, so it can be free
end of the function
