scsi: mptfusion: Remove unnecessary parentheses
Clang warns when multiple pairs of parentheses are used for a single
conditional statement.
drivers/message/fusion/mptbase.c:338:11: warning: equality comparison
with extraneous parentheses [-Wparentheses-equality]
if ((ioc == NULL))
~~~~^~~~~~~
drivers/message/fusion/mptbase.c:338:11: note: remove extraneous
parentheses around the comparison to silence this warning
if ((ioc == NULL))
~ ^ ~
drivers/message/fusion/mptbase.c:338:11: note: use '=' to turn this
equality comparison into an assignment
if ((ioc == NULL))

Remove them and while we're at it, simplify the NULL checks as '!var' is
used more than 'var == NULL'.
