net/qla3xxx: Fix a test in ql_reset_work()

[ Upstream commit 5361448e ]

test_bit() tests if one bit is set or not.
Here the logic seems to check of bit QL_RESET_PER_SCSI (i.e. 4) OR bit
QL_RESET_START (i.e. 3) is set.

In fact, it checks if bit 7 (4 | 3 = 7) is set, that is to say
QL_ADAPTER_UP.

This looks harmless, because this bit is likely be set, and when the
ql_reset_work() delayed work is scheduled in ql3xxx_isr() (the only place
that schedule this work), QL_RESET_START or QL_RESET_PER_SCSI is set.

This has been spotted by smatch.
