[PATCH] xen/common: fix MISRA R7.2 violations in crc32/unlzma/bunzip2

[Andrew Mbugua <andrewprecious388@xxxxxxxxx>]

Adding the U suffix. No functional change.

MISRA C Rule 7.2 demands a "u" or "U" suffix on all
integer constants with unsigned type. On 32-bit int targets
constants >= 0x80000000 (e.g. 0xEDB88320, 0xFFFFFFFF,
0x80000000, 0x04C11DB7) must be written explicitly unsigned.
