[AArch64] Fix incorrect mask when decoding b.cond instruction
The encoding of the b.cond instruction is described in the architecture
reference manual as:
b.cond 0101 0100 iiii iiii iiii iiii iii0 cccc
So the mask should be 0xff000010.
gdb/ChangeLog:
* aarch64-tdep.c (decode_bcond): Fix incorrect mask.
