Input: rmi4 - use devm_kmalloc for F12 data packet buffer

The sensor->data_pkt buffer is used exclusively to store incoming
hardware data during the attention handler, where it is entirely
overwritten by either memcpy() or rmi_read_block(). Therefore,
there is no need to zero-initialize it during probe.

Switch to devm_kmalloc() to avoid the unnecessary memset overhead.
