Colin Ian King 438bf726de ipmi_si: fix potential integer overflow on large shift
[ Upstream commit 97a103e6b584442cd848887ed8d47be2410b7e09 ]

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.

Detected by CoverityScan, CID#1465246 ("Unintended sign extension")
