ata: libata: Fix memory leak for error path in ata_host_alloc()
In ata_host_alloc(), if devres_alloc() fails to allocate the device host
resource data pointer, the already allocated ata_host structure is not
freed before returning from the function. This results in a potential
memory leak.
Call kfree(host) before jumping to the error handling path to ensure
that the ata_host structure is properly freed if devres_alloc() fails.
Fixes: 2623c7a5f279 ("libata: add refcounting to ata_host")
