tfd is one data field of FIS for AHCI, it is unacceptable if it is
random value, could cause AHCI data transport failure.
Acturally there is no chance the switch statement has the value other
than 0~3, since there is only 2 bit to deduce.
Add the initial value for tfd as ATA_S_ERROR, which is checked by
function ahci_write_fis_d2h afterwards, so guest driver could handle it well.

int snprintf(char *str, size_t size, const char *format, ...)
The functions snprintf() write at most size bytes (including the
terminating null byte('\0')) to str.
only when returned value of snprintf is non-negative and less than size,
the string has been completely written.

There are two build issues:
- add -fno-strict-aliasing to address
error: dereferencing type-punned pointer will break strict-aliasing rules
- initialize tfd to zero to address
error: ‘tfd’ may be used uninitialized in this function

This reverts commit bc0579d0ff.
The commit bc0579d makes acrn-dm crashed when launch UOS.
Crash log:
./launch_UOS.sh: line 112: 377 Segmentation fault (core dumped) acrn-dm ...
dmesg log:
acrn-dm[1264]: segfault at 1f0 ip 0000000000412257 sp 00007fffc1af9920 error 6 in acrn-dm[400000+3d000]
After this patch reverted, UOS launched successfully.
A couple of problems appeared on Ubuntu 14.04 (gcc 4.8.4) when we
turned on additional compiler flags with commit
519c4285cf. This patch fixes these
problems by adhering to the strict anti-aliasing rules and also
initializing the 'tfd' variable where the compile believed it
_could_ be used uninitialized.
