x86/extable: switch to using FIELD_GET_SIGNED()
The EX_DATA register is laid out such that EX_DATA_IMM occupied MSB.
It's done to make sure that FIELD_GET() will sign-extend the IMM
field during extraction.
To enforce that, all EX_DATA masks are made signed integers. This
works, but relies on the particular implementation of FIELD_GET(),
i.e. masking then shifting, not vice versa; and the particular
placement of the fields in the register.
Switch to using the dedicated FIELD_GET_SIGNED(), and relax those
limitations.
