hw/sd/sdcard: Rename Write Protect Group variables

Browse source 
'wp_groups' holds a bitmap, rename it as 'wp_group_bmap'.
'wpgrps_size' is the bitmap size (in bits), rename it as
'wp_group_bits'.

Patch created mechanically using:

  $ sed -i -e s/wp_groups/wp_group_bmap/ \
           -e s/wpgrps_size/wp_group_bits/ hw/sd/sd.c
