xtensa: stop filling syscall array with sys_ni_syscall
arch/xtensa/kernel/syscalls/syscalltbl.sh fills missing syscall numbers
with sys_ni_syscall.
So, the generated arch/xtensa/include/generated/asm/syscall_table.h
has no hole.
Hence, the line:
[0 ... __NR_syscalls - 1] = (syscall_t)&sys_ni_syscall,
is meaningless.
The number of generated __SYSCALL() macros is the same as __NR_syscalls
(this is 442 as of v5.11).
Hence, the array size, [__NR_syscalls] is unneeded.
The designated initializer, '[nr] =', is also unneeded.
This file does not need to know __NR_syscalls. Drop the unneeded
<asm/unistd.h> include directive.
