nvme-pci: fix early boot hang with nvme.quirks parameter

Passing nvme.quirks on the kernel command line causes a silent boot
hang when the NVMe driver is compiled as a built-in module.

This happens because the parameter is currently registered using
module_param_cb(). For built-in modules, this macro flags the parameter
to be evaluated at initcall level -1. Consequently, quirks_param_set() is
called before the memory allocators are initialized.

Fix this by replacing module_param_cb() with device_param_cb(). This
defers the parameter parsing to initcall level 6, guaranteeing that
the system memory allocators are fully functional before the quirk
string is parsed and allocated.
