[PATCH 5/5] soc: fsl: dpaa2-console: free buffer before returning from dpaa2_console_read

[Ioana Ciornei]

From: Robert-Ionut Alexa <robert-ionut.alexa@xxxxxxx>

Free the kbuf buffer before returning from the dpaa2_console_read()
function. The variable no longer goes out of scope, leaking the storage
it points to.

Fixes: c93349d8c170 ("soc: fsl: add DPAA2 console support")
