f2fs: fix nandroid restore to f2fs partitions

Change-Id: I7bf243045748949766e0128662e66dfc04378d06
Match AOSP get/set_bootloader_message() layouts

No change in behavior, just matching AOSP's code layout. LOGE has been
changed to LOGI for "Cannot load volume /misc!" since many devices do
not define a /misc partition in fstab.

Remove obsolete check on device_flash_type() before trying to read args from BCB

get_bootloader_args() has handled the case where the misc partition
doesn't exist or is an unknown type since 7501798f... ("Fix nullpointer
when recovery.fstab does not define a "misc" partition") all the way
back in 2010, and we use set_bootloader_args() below unconditionally
anyway.  Remove this obsolete check.
