net: jme: remove unused initialization of 'rxdesc'

Colin Ian King · davem330 · commit f14d244f6147 · 2018-02-01T14:54:28.000-05:00
Pointer rxdesc is assigned a value that is never read, it is overwritten
by a new assignment inside a while loop hence the initial assignment
is redundant and can be removed.

Cleans up clang warning:
drivers/net/ethernet/jme.c:1074:17: warning: Value stored to 'rxdesc'
during its initialization is never read
