EDAC/i10nm: Fix the bitwise operation between variables of different sizes

The tool of Smatch static checker reported the following warning:

  drivers/edac/i10nm_base.c:364 show_retry_rd_err_log()
  warn: should bitwise negate be 'ullong'?

This warning was due to the bitwise NOT/AND operations between
'status_mask' (a u32 type) and 'log' (a u64 type), which resulted in
the high 32 bits of 'log' were cleared.

This was a false positive warning, as only the low 32 bits of 'log' was
written to the first RRL memory controller register (a u32 type).

To improve code sanity, fix this warning by changing 'status_mask' to
a u64 type, ensuring it matches the size of 'log' for bitwise operations.
