serial: Fix potential null-ptr-deref in mlb_usio_probe()
[ Upstream commit 86bcae88c9209e334b2f8c252f4cc66beb261886 ]
devm_ioremap() can return NULL on error. Currently, mlb_usio_probe()
does not check for this case, which could result in a NULL pointer
dereference.
Add NULL check after devm_ioremap() to prevent this issue.
Fixes: ba44dc043004 ("serial: Add Milbeaut serial control")
