spi: dln2: Fix reference leak to master
[ Upstream commit 9b844b087124c1538d05f40fda8a4fec75af55be ]
Call spi_master_get() holds the reference count to master device, thus
we need an additional spi_master_put() call to reduce the reference
count, otherwise we will leak a reference to master.
This commit fix it by removing the unnecessary spi_master_get().
