Change the 'ret' variable from u32 to int in nct6775_asuswmi_read() to
store negative error codes or zero;

Storing the negative error codes in unsigned type, doesn't cause an issue
at runtime but can be confusing. Additionally, assigning negative error
codes to unsigned type may trigger a GCC warning when the -Wsign-conversion
flag is enabled.

No effect on runtime.
