ipmi_si: fix potential integer overflow on large shift
Shifting unsigned char b by an int type can lead to sign-extension
overflow. For example, if b is 0xff and the shift is 24, then top
bit is sign-extended so the final value passed to writeq has all
the upper 32 bits set. Fix this by casting b to a 64 bit unsigned
before the shift.
