spi-sd-card: disk device barfs on low-capacity 2GB cards

Description

The SPI SD card driver sets the block size of low-capacity 2GB cards to 512 bytes even though the card reports 1024 bytes. However, the number of blocks should then also be doubled.

Failing that, the disk device layer (rtems_disk_create_log()) barfs because the partition size is larger than the disk size.

Low capacity 2GByte cards are set back to block size 512, so block_number should be doubled.
