hujun5 79b6d27018 arm64: fix SP_EL0 register handling in syscall return path 
Use regs[REG_SP_EL0] from register context instead of direct sp_el0 system
register read/write operations in arm64_syscall(). Replace read_sysreg(sp_el0)
with regs[REG_SP_EL0] and write_sysreg(usp, sp_el0) with direct assignment to
regs[REG_SP_EL0]. Ensures userspace stack pointer is correctly maintained from
register context during signal delivery, preventing userspace SP corruption on
syscall return.
