_ux_utility_mutex_on() function called from ISR fails with TX_WAIT_ERROR #117

Trying to get one of the STM32 USBX examples available here (MSC host) I stumbled upon an error which probably should not have happen. Within _ux_utility_mutex_on() function tx_mutex_get() is called with TX_WAIT_FOREVER option which results in TX_WAIT_ERROR error since the call originated from OTG_FS_IRQHandler ISR. I think this may be a bug. USBX version is 6.2.0, compiler GCC.
