h264: Fix a typo from the previous commit

f777504f640260337974848c7d5d7a3f064bbb45 changed a - in +

CC: libav-stable@libav.org
lavr: add a function for checking whether AVAudioResampleContext is open
lavr: return an error if a avresample_open() is called on an open context
hevc: Drop unnecessary shifts in deblocking_filter_CTB

beta_offset is pre-multiplied by 2.
hevc: Do not right shift a negative value in get_pcm
hevc: Do not left shift a negative value in hevc_loop_filter_chroma
configure: disable cpunop if the check fails

Moving cpunop from the HAVE_LIST to the ARCH_EXT_LIST_X86 has the side
effect of enabling it. The semantics of the check have to be changed
from enable if successful to disable if unsuccessful. This was missing
in 2b0bb69997c2416e74f41aa1400ce983bf8775c0 causing build errors with
nasm.
