soc: fsl: dpaa2-console: free buffer before returning from dpaa2_console_read
[ Upstream commit 8120bd469f5525da229953c1197f2b826c0109f4 ]
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")
