Input: synaptics-rmi4 - fix an unchecked out of memory error path

[ Upstream commit 839c42273617787318da7baf6151d553108f5e17 ]

When extending the rmi_spi buffers, we must check that no out of memory
error occurs, otherwise we may access data above the currently allocated
memory.

Propagate the error code returned by 'rmi_spi_manage_pools()' instead.
