scsi: mptfusion: Remove unnecessary parentheses 

Clang warns when multiple pairs of parentheses are used for a single
conditional statement.

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

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