When calculating the offsets for the current entry within the row and
placing them inside struct vcap_data, the function assumes half key
entry (2 keys per row).
This patch modifies the vcap_data_offset_get() function to calculate a
correct data offset when the setting VCAP Type-Group of a key to
VCAP_TG_FULL or VCAP_TG_QUARTER.
This is needed because, for example, VCAP ES0 only supports full keys.
Also rename the 'count' variable to 'num_entries_per_row' to make the
function just one tiny bit easier to follow.
