can: mscan: mpc5xxx: mpc5xxx_can_probe(): add missing put_clock() in error path

Browse Source 
[ Upstream commit 3e5b3418827cefb5e1cc658806f02965791b8f07 ]

The commit 1149108e2f ("can: mscan: improve clock API use") only
adds put_clock() in mpc5xxx_can_remove() function, forgetting to add
put_clock() in the error handling code.

Fix this bug by adding put_clock() in the error handling code.
