serial: qcom_geni: Fix variable naming

Commit 2aaa43c70778 ("tty: serial: qcom-geni-serial: add support for
serial engine DMA") renamed rx_fifo member to rf_buf which caused a
build failure when b8caf69a6946 ("tty: serial: qcom-geni-serial: fix
slab-out-of-bounds on RX FIFO buffer") from tty-linus was merged into
tty-next.

Fix the member variable name.

Fixes: 7a6aa989f2e8 ("Merge 6.2-rc5 into tty-next")
