Bart Van Assche d7afd7d3e3 Input: synaptics-rmi4 - fix a locking bug in an error path
commit 7adaaee5ed upstream.

Lock f54->data_mutex when entering the function statement since jumping
to the 'error' label when checking report_size fails causes that mutex
to be unlocked.

This bug has been detected by the Clang thread-safety checker.
