spi: cadence-quadspi: Remove spi_master_put() in probe failure path 
Currently the spi_master is allocated by devm_spi_alloc_master()
and devres core manages the deallocation, but in probe failure
path spi_master_put() is being handled manually which causes
"refcount underflow use-after-free" warning when probe failure happens
after allocating spi_master.

Trimmed backtrace during failure:

refcount_t: underflow; use-after-free.
pc : refcount_warn_saturate+0xf4/0x144
Call trace:
refcount_warn_saturate
kobject_put
put_device
devm_spi_release_controller
devres_release_all

This commit makes relevant changes to remove spi_master_put() from probe
failure path.

Fixes: 606e5d408184 ("spi: cadence-quadspi: Handle spi_unregister_master() in remove()")
