To reduce type conversion in HV:
Update return type of function ffs64 and ffz64 as uint16;
For ffs64, when the input is zero, INVALID_BIT_INDEX is returned;
Update temporary variable type and return value check of caller
when it call ffs64 or ffz64;
Note: In the allocate_mem, there is no return value checking for
calling ffz64, this will be updated latter.
V1-->V2:
INVALID_BIT_INDEX instead of INVALID_NUMBER
Coding style fixing;
INVALID_CPU_ID instead of INVALID_PCPU_ID or INVALID_VCPU_ID;
"%hu" is used to print vcpu id (uint16_t);
Add "U/UL" for constant value as needed.
V2-->V3:
ffs64 return INVALID_BIT_INDEX directly when
the input value is zero;
Remove excess "%hu" updates.
V3-->V4:
Clean up the comments of ffs64;
Add "U" for constant value as needed.
