misc: pci_endpoint_test: Remove global 'irq_type' and 'no_msi'

The global variable "irq_type" preserves the current value of
ioctl(GET_IRQTYPE).

However, all tests that use interrupts first call ioctl(SET_IRQTYPE)
to set "test->irq_type", then write the value of test->irq_type into
the register pointed by test_reg_bar, and request the interrupt to the
endpoint. The endpoint function driver, pci-epf-test, refers to the
register, and determine which type of interrupt to raise.

The global variable "irq_type" is never used in the actual test,
so remove the variable and replace it with "test->irq_type".

Also, for the same reason, the variable "no_msi" can be removed.

Initially, "test->irq_type" has IRQ_TYPE_UNDEFINED, and the
ioctl(GET_IRQTYPE) before calling ioctl(SET_IRQTYPE) will return
an error.
