tcm-file: Set fd_buffered_io=1 based upon active FILEIO mode
tcm-file: Set fd_buffered_io=1 based upon active FILEIO mode

This patch fixes a bug in fd_get_params() where FILEIO buffered enabled mode
was not being saved across reboots in /etc/target/tcm_start.sh, causing
FILEIO devices created with buffered=true to revert to O_DSYNC mode.
