Change the unused var in 'arch/x86/entry/syscalls/syscalltbl.sh' to '_'
when reading from '$sorted_table'. This change allows the script to pass
tests of ShellCheck before and after version 0.7.2 at the same time.
When building in arch x86, syscalltbl.sh got a ShellCheck warning, which
makes compilation error:
In arch/x86/entry/syscalls/syscalltbl.sh line 27:
while read nr _abi name entry _compat; do
^-^ SC2034: abi appears unused.
Verify use (or export if used externally).
^----^ SC2034: compat appears unused.
Verify use (or export if used externally).
The script reads unused param abi and compat. It uses format '_xxx' to
indicate dummy vars, which won't work properly when ShellCheck <= 0.7.2.
According to SC2034, the more general way of writing is to use directly
'_' to indicate discarding vars. 'entry' is also replaced by '_' because
it just happens to be defined in emit function, otherwise it will lead
to some misunderstandings.
