jbig2dec: Remove check for bitmap coding context use.

The removed check used bitmask 0x80 to check for the flag
"bitmap coding context used" among the symbol dictionary flags.
The correct bitmask is 0x100, which was already checked for
later in the code, rendering this incorrect check unnecessary.
