fix: bsp/stm32: drv_qspi: zero-initialize qspi_device struct

[jiaoxy0]

rt_hw_qspi_device_attach() allocates qspi_device via rt_malloc() but does not zero it, leaving uninitialized fields with random values. This can cause undefined behavior when fields like enter_qspi_mode are checked before being explicitly set.

Fix: Add rt_memset() right after allocation and error check.

• 看着不是很有必要的样子
• 如果要做使用alloc在分配时直接清零更好
• 而且要修改就对stm32的驱动都进行扫描都去修改

• 在MCU不掉电软重启的情况下，会出bug，因为这种情况下那块内存中的初始化标志没被清零，会导致软重启后误判已经初始化，我在实际使用过程中遇到了这个bug
• 我按照您后两条建议重新修改一下
