scsi: mpt3sas: Remove unnecessary parentheses and simplify null checks 

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

drivers/scsi/mpt3sas/mpt3sas_base.c:535:11: warning: equality comparison
with extraneous parentheses [-Wparentheses-equality]
        if ((ioc == NULL))
             ~~~~^~~~~~~
drivers/scsi/mpt3sas/mpt3sas_base.c:535:11: note: remove extraneous
parentheses around the comparison to silence this warning
        if ((ioc == NULL))
            ~    ^      ~

equality comparison into an assignment

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