Restore EAX value before returning sprint

[NeoSahadeo]

Howdy,

Not sure if this is an issue-issue but the value in sprint for EAX is never restored which causes segfaults on repeated calls.

; void sprint(String message)
; String printing function

    push    edx
    push    ecx
    push    ebx
    push    eax

    mov     edx, eax
    pop     eax
 
    mov     ecx, eax
    mov     ebx, 1
    mov     eax, 4
    int     80h
 
    mov     eax, ecx ; <---- restore the contents of eax
    pop     ebx
