Subject: [PATCH 1/2] syscall.h: Remove unused SYSCALL_MAX_ARGS

The "SYSCALL_MAX_ARGS" appears to have been unused since
commit 32d92586629a ("syscalls: Remove start and number from
syscall_set_arguments() args"), so remove it.

Fixes: 32d92586629a ("syscalls: Remove start and number from syscall_set_arguments() args")
